What are the different forms of marijuana

Cannabis: forms, effects and risks

In Latin, cannabis refers to the hemp plant. In Germany, this primarily includes products made from hemp that contain THC. The dried flowers of the female plant are the basis for marijuana. They carry glands that contain resin with THC, CBD, and other cannabinoids. These pervade the plant in 60 different forms - one of them, THC, is psychoactive.

Marijuana and hashish

Marijuana varies in color from whitish to brown and green to light purple tones. The color depends on the origin, the cultivation method and the dryness of the fabric. Hashish, on the other hand, refers to the pressed resin of the flowers and leaves. The color ranges from gray-brown to a dull black and a glossy black if there is a lot of so-called hash oil. Hashish has a crumbly to firm consistency, and depending on the degree of freshness it can be greasy or even a paste. For sale it is pressed into plates, rolled into balls or sticks (sausages).

It can be mixed with tobacco and smoked in cigarette papers as a joint. However, this method is relatively new - the traditional hashish cultures in Morocco, Lebanon, Pakistan or Afghanistan used pipes with long stems, so-called shillums, i.e. tubes that widen towards the end, or the shisha known as water pipes. Hash can also be eaten, for example in biscuits or in tea.


Tetra hydrocamabinol (THC) is the main substance in hemp. The THC content varies considerably with the individual hemp varieties. Plants that are approved as useful plants in Germany but are not allowed to be used for hashish production contain around 1.5% THC, varieties in Iran or Afghanistan over 5% and new "high-performance breeds" over 20%.

A medicine

Uruguay now offers marijuana in pharmacies at a price of around one euro. The aim of this legalization is on the one hand to dry up the illegal market and on the other hand to offer the sick a medically effective substance. In Germany, cannabis is only allowed to be sold for purely medical purposes, and the necessity is checked by a doctor on individual patients. Currently there are a few hundred pain patients and multiple sclerosis sufferers who receive cannabis on a medical certificate. In fact, the substance has been known for thousands of years as a pain reliever.

Canada, Israel, the Netherlands and the Czech Republic go much further than Germany in legalizing THC-containing hemp, but not as far as Uruguay. Cannabis is permitted for medical purposes in 20 states in the USA and is mainly used for headaches and insomnia.

Indians and China already cultivated hemp 5000 years ago, on the one hand they used the fibers for clothes and baskets, on the other hand they used the plant as a medicine.


The body itself produces cannabinoids, which are similar to the substances in hemp. They have an effect on the vegetative nervous system and lead to a slight euphoria such as relaxation, and they also change the perception of colors and sounds, so they are hallucinogens.

Long-term use of cannabis can negatively affect memory and concentration. In the long run, the hallucinogenic quality harbors the risk of chronic psychological changes and even lasting psychoses.

Hash oil

Of all cannabis products, hash oil has the strongest effect, because it is an extract of the THC-containing resin, so not a real oil. The content of the active ingredient can be 70%. Samples from the Federal Criminal Police Office were between 5 and 41%.

Cannabis oil is usually golden yellow in color and is liquid. One drop in a joint is enough to achieve the desired effect. It is also banned in Germany in small quantities.

Medicinal effect

Although hemp has been used in medicine for thousands of years, its effect as a medicine has not been adequately researched. The cannabinoid CBD does not induce a high, but it is believed to be effective against inflammation, arthritis and nerve pain. It also reduces the symptoms of mental illnesses such as bipolar disorder.

The discussion about the legalization of cannabis is highly ideological in western countries, and that is one reason why a factual examination of cannabis in medicine is pending: Opponents demonize the substance, proponents praise hemp as a miracle cure against anything and everything.

No side effects?

An American study with a hundred cannabis users suggests that long-term consumption inhibits the development of white blood cells, weakens the immune system, and makes those affected susceptible to various diseases.

Cannabis also appears to reduce the production of the male sex hormone testosterone, so chronic use could damage male potency. Just like alcohol, it degrades sex drive.

Is cannabis addictive?

The strength of a drug differs classically, among other things, whether it is not at all, “only” psychologically or physically dependent. Today, however, neurosciences prove that the strict separation between physical and psychological cannot be maintained: Psychological processes lead to biochemical changes in the body, physical processes go hand in hand with changes in the psyche.

The situation is similar with psychological dependence: a person who feels psychologically dependent on something shows physical symptoms - the body now releases hormones when it only thinks about the substance. Researchers in San Francisco assume that hashish is also physically addictive in the long term. Addicts would experience the same withdrawal symptoms as they would with hard drugs.

Another undesirable side effect is the information overload. In the long run, cannabis users can hardly distinguish between important and unimportant information.

Hashish - resin in a thousand forms

The yellow-brown hashish platter typically comes from Morocco. The traditional growing area is in the central Rif Mountains. In the past few decades, producers have introduced hybrid varieties and artificial irrigation, and both of these together have increased the quality and quantity of the Moroccan fabric.

Zero-Zero is pure hashish from the resin gland head after the first sieving. It doesn't last long, but it has a very psychedelic effect.

Double Zero-Zero stands out due to its excellent quality, contains almost no foreign dust or plant parts. Normal zero arises after the second sieving and contains more flower parts, but is cheaper. Casablanca corresponds to this type and tastes similar to ginger in tea.

Sputnik is dark brown, very resinous and comes from the high elevations of the Rif Mountains, Chocolata has a greenish-black color, is picked before the actual harvest, is of the best quality, and that's why Moroccans usually consume it themselves. Black Moroccan smells of mint and has a strong effect psychedelic. Agadir, named after the tourist stronghold on the Atlantic, is dark with a sweet taste.

Pakistani, Afghan, Arab or Kashmiri not only stand for the origin, but also for effective hashish with a dark color.

"Balls" are very potent hashish that comes in balls that can be kneaded by hand. Caramellos are hand-rolled "sausages" that are placed in hash oil.

King Mohammed describes a high-quality light hashish, King Hassan II a darker one. Sierra Ketana stimulates and relaxes.

Puck is meant derogatory. It refers to dark brown material that is very stretched and scratches the throat when smoked.

Egg morocco is artificial hash in the sense that hash oil is dripped onto plant fibers.

Green Turk and Red Lebanese

Green Turk comes from Turkey, was widespread in Germany until the 1970s, but was pushed out of the Turkish market by the more lucrative heroin trade. "Kurd", hashish from the Diyarbakir region, is currently rampant in this country.

“Lebanese” is hardly on the market anymore due to the “war against drugs” in Lebanon. It has a red color, a high CBD content as well as a high THC content, which, according to users, leads to mental clarity in physical indolence, i.e. a state of drowsiness.

Black Afghan hounds are black on the outside and brownish on the inside. It has an intense smell, a high THC content and is usually made supple with sheep or goat fat. The Afghan burns very slowly and heavily and makes you tired quickly. The same goes for Black Pakistani, which, however, has a harder consistency.

Bhang and Chassas

India is one of the hashish centers in the world. Oral ingestion of products made from the leaves is legal here, and this bhang is sold in state-licensed stores. Hashish oil and hashish, on the other hand, are illegal, as is the sale of female inflorescences. Chassas, the Indian term for hashish, are available on the subcontinent as sticks or strips.

Further spectra of the hashish varieties include “Tibetans”, “Nepalese”, “Jamaicans”, “Mexicans”, “Yunanni” or “Bhutani”, all of which refer to the countries of origin.

CBD (cannabidiol)

Cannabis with THC is only legally available in Germany with a prescription. Recently, hemp products with the active ingredient cannabidiol (CBD) can also be found in drugstores. Recent research suggests that CBD is a good anti-inflammatory, pain reliever, and may positively affect mood. Since it does not contain THC, there is no intoxication. If taken regularly, a doctor should be consulted, as CBD can interact with other drugs. For example, cannabidiol changes the effect of blood thinners and some chemotherapy drugs used to treat cancer.
