Smoking medical marijuana may not be enough to effectively fight cancer, severe pain, siezures and symptoms of many other diseases. Most of the cannabis medication is waste into the air when smoked and it is not really healthy to smoke anything.
Slide 14: Marijuana smoke contains cancer-causing substances
Some research shows that marijuana smoke has up to 70% more cancer-causing substances than tobacco smoke, it says. Long-term, heavy use of marijuana can lead to impaired thinking skills and memory problems,
That is thought to be due to differences in tolerance, smoking technique,
and the potency of the marijuana.
Numerous studies have linked marijuana use with schizophrenia. In this braindisorder, people may think they hear voices and that others are controlling their minds and thoughts.
However, Lamarine suspects the relationship may be reversed. "What I suspect is, people who are going to develop full-blown schizophrenia must feel bad beforehand," he says. They may be attracted to marijuana as a mood-altering drug to self-medicate.
If this link were cause and effect, Armentano says, the rates of schizophrenia would have climbed, as marijuana use has increased.
Marijuana use can be linked with anxiety, Lamarine and Armentano agree.
Several published studies, Lamarine says, have found a link between marijuana use and anxiety, but not necessarily full-blown anxiety disorders.
Studies have also found a link between regular marijuana use and panic attacks.
Some marijuana users do have panic attacks, especially if they are new to the drug, Armentano says.
As for the anxiety-marijuana link, he says, it could be that some anxious people try marijuana to self-medicate.
Those who have known psychotic problems should proceed with caution when thinking about marijuana use, Armentano says
