Cannabis refers to the hemp plant and is one of the oldest useful and medicinal plants and intoxicants. Worldwide, cannabis is the most widespread illegal, psychoactive substance. Almost 40 % of Swiss people aged 15 and over and about a quarter of Swiss women have tried cannabis at least once.

Mostly cannabis is smoked in the form of joints. But it can also be eaten (e.g. in pastries) or smoked or vaporised in shishas, bongs and vaporizers.

Cannabis contains about 400 substances. One of them is THC (delta-9-tetrahydrocannabinol), which causes the intoxicating effect. CBD (cannabidiol) is also a constituent of the plant, which has no psychoactive effect, which is why CBD cannabis does not fall under the Narcotics Act.

Consumers often seek the relaxing, disinhibiting effect of cannabis. However, (especially long-term and intensive use) the use also carries the danger of dependence and other risks (psychological, physical, social).

One danger that is currently in focus is synthetic cannabinoids, with which cannabis is mixed on the black market and which can cause severe poisoning and even death.

If you need more information, want to reflect your use, experience negative consequences of your use, want to change it or stop it, then you have come to the right place.
