[Commonplace use of "H"].
OBJECTIVE
Describe characteristic use of cannabis and tobacco.


METHODS
A young couple were nicotine-dependent smokers who also regularly used cannabis. After treatment for nicotine withdrawal they no longer had a craving for cigarettes but use of hashish increased.


CONCLUSIONS
Although illegal in France, consumption of cannabis has become commonplace. Short-term risk may be low but the liposolubility of hallucinogenic tetrahydrocannabinol retards elimination leading to the risk of neuropsychiatric disorders after chronic, or even episodic use.
