Occasional Marijuana Use 'does Not Harm Teens': Study

[Medical Marijuana]

Swiss teenagers who sometimes smoke marijuana don't appear to have higher rates of "psychosocial problems" than those who abstain, according to a study published today in the Archives of Pediatrics and Adolescent Medicine.

"Those who use cannabis sometimes do better than we think," J.C. Suris, the study's author, said in an interview. Light users of marijuana "don't have great additional problems. They are kids who function well."

The study also found that teenagers who smoke both marijuana and cigarettes have a higher potential for problems than those who use only cannabis. A common theory is that cigarette smoking is an early indicator of cannabis use, the report said.

"Among cannabis users, non smokers seem to have fewer problems than regular smokers," the report said. "Smokers were significantly more likely to be heavy cannabis users than non smokers."

Most of the cannabis-only smokers used the drug only once or twice a month, compared with cigarette smokers, who often smoked marijuana 10 times or more a month, the study said.

The study was conducted on students ages 16 to 20 who completed surveys. While teenage exaggerations could have occurred, those should be minimal because the surveys were anonymous, the study said. School dropouts, who are known to be heavier substance users, weren't surveyed, the study said.

About 455 said they only used marijuana, while 1,703 smoked both cigarettes and pot. The other 3,105 said they abstained from both substances.

When teenagers who smoke only pot were compared with students who used both substances, the cannabis-only students were more likely to play sports, 86 per cent versus 67 per cent; live with both parents, 78 per cent versus 68 per cent; and have good grades, 78 per cent versus 67 per cent.

Marijuana-only users, when compared with those who abstained from both vices, were more likely to be male, 72 per cent versus 48 per cent; to have good relationships with their friends; 87 per cent versus 83 per cent; and to play sports, 86 per cent versus 77 per cent.

The pot-only smokers skipped school more often while saying their grades were as good as those of students who abstained, the study said. The pot-only kids were less likely to have a good relationship with their parents, 74 per cent versus 82 per cent for those who abstained.

Unlike in the US, cannabis use has increased in Switzerland and other European countries, the report said. Cannabis in Switzerland is becoming equivalent to a social event where teenagers might invite friends for joints rather than beers, Suris said.

"Nowadays, almost all kids will be offered cannabis," Suris said in an interview. He advises parents that if their children try marijuana, "don't make it a big fuss. It's part of their learning, maybe like alcohol or tobacco was when parents were their age."

What researchers are not clear about is whether poor grades cause students to become heavier users of pot or if the marijuana usage itself causes the poor grades, he said. Suris said a follow-up study should be conducted to find out how the teenagers fared.
