Then tell us what are the always toxic effects of marijuana? You give us stuff largely related to how the drug is taken and bunch of vague stuff about how it MAY affect people with pre-existing conditions.
So, it's probably not a good idea to smoke Viagra or take it if you have a heart condition. The rest of us will be on the lookout for that four-hour boner and putting out the do not disturb sign.
There are possible negative health effects, but they are relatively minor, and individuals are quite capable of making their own rational decisions on whether to use or not. Read the sign.
I pasted some information based on a Google search because Billy asked for information/instances that cited problems with marijuana.
I boldened the parts that indicated at this juncture no precise facts are known since they haven't been studying the ill effects of marijuana use as long as they have cigarette use.
Just because there isn't definitive proof that marijuana is dangerous because it's not in an AMA study, or in years of rigourous clinical studies conclusively determining it's dangerous, does not mean IN MY HUMBLE ESTIMATION, that it isn't harmful or dangerous.
The irony is that for decades they said the same happy horse$hit about cigarette smoking and it didn't stop people from dying from lung cancer, or alter the fact that once the studies were concluded that all along it was bad for you and definitively contributed to lung cancer deaths.
I am sure there were millions who wanted to believe the same happy horse$hit that marijuana smokers now want to believe. They too continued to puff away, day in day out, substantiating killing themselves due to lack of clinical data.
I don't smoke dope. I think smoking dope is for dopes unless it is for a bonafide medical reason. That being said, I am not telling anyone they can't toke away until the time comes, and it will come, when they finally tell you all those years when there was no definitive proof it really WASN'T good for you after all.
You inhale any burning weed; I don't care if it's horse$hit or genetically enhanced super bud, hold it down in your lungs for an extended period of time, daily and for years on end and think it's long term effects are neglible, isn't just silly, it's stupid.
I don't need a report from the AMA to decide that for me. It's effin' common sense!
