Individual Toxicity

The smoked use of cannabis is not without hazards which should be clearly recognized so as to permit appropriate action to avoid or minimize these untoward effects.

Physical Effects

The smoke of cannabis is irritating to the mouth, throat, trachea, bronchii, and lungs. The level of irritation is comparable to that of tobacco with the level of irritation dependent upon the amount of exposure, heat of the smoke and degree of impurity. Because of it's illegality it is not yet possible to scientifically document the possible connection with actual lung disease.

For similar reasons it is not possible to determine possible adverse effects upon passive exposure to marijuana smoke.

There are some people that are allergic to marijuana smoke and develop hives or asthmatic symptoms when exposed to it.

Mental Effects

Cannabis when smoked may cause confusion and disorientation in the inexperienced or sensitive user.
