e-prevention and risk reduction in festive environments. Know more, risk less


Whatever your motivation to view this page, whether you have decided to buy cannabis or use products listed on our website, or for your personal interest to inform yourself or by concern for someone around you, we provide answers and leads about risk and damage reduction to limit aggravating factors related to cannabis consumption.

Cannabis is a plant (Indian hemp). One of its ingredients is THC (delta-9-tetrahydrocannabinol). It has psychoactive effects and affects the central nervous system.

It is mostly smoked (joint, water pipe) but can also be drunk, eaten (space cake) or inhaled. You can encounter several forms of cannabis such as dried plant (weed, grass, ganja), resin (hashish, shatter, wax) and hash oil.


Cannabis/Marijuana brings relaxation, calming down and euphoria. It distorts perception and stimulates odd image associations and communication. It whets appetite and has an disinhibiting effect that can boost sociability and bonding.


Cannabis/Marijuana can have unsettling if not nerve-wracking effects. Varieties with high levels of THC (skunk for example) magnify them. Some can experience a sudden loss of balance, nausea with dizziness, cold sweat and drowsiness. Others can feel excitation or anxiety. Regular cannabis consumption can lead to a psychological addiction that can be very difficult to handle.

It can favour memory and attention losses, apathy and lack of motivation (studies, work, family, friends, sport). Tobacco is often paired with cannabis and the tar contained in the cigarette smoke is carcinogenic.


For some users, anxious states can evolve in anxiety and paranoia attacks. Hash oil, highly THC-concentrated products or consumption practices aimed at increasing the dose in one take (bong, blowbacks, shotgun weed, blunt, brownies) can cause very disturbing auditory and visual hallucinations. Those practices can lead to “bad trips” or acute poisoning. Cannabis can also trigger and worsen schizophrenia manifestations. THC, the active principle of marijuana, is eliminated from the body after several weeks only: it can therefore be detected way after consumption.
