Medical Marijuana Pros
"There is very little evidence that smoking marijuana as a means of taking it represents a significant health risk.
Although cannabis has been smoked widely in Western countries for more than four decades, there have been no reported cases of lung cancer or emphysema attributed to marijuana.
I suspect that a day's breathing in any city with poor air quality poses more of a threat than inhaling a day's dose -- which for many ailments is just a portion of a joint -- of marijuana."
- Dr. Lester Grinspoon
Medical Marijuana Cons
"Although I understand many believe marijuana is the most effective drug in combating their medical ailments, I would caution against this assumption due to the lack of consistent, repeatable scientific data available to prove marijuana's medical benefits.
Based on current evidence, I believe that marijuana is a dangerous drug and that there are less dangerous medicines offering the same relief from pain and other medical symptoms."
- Dr. Bill Frist
• Medicinal legalization potentially undercuts the message that controlled substances are dangerous.
