I've rehabilitated hundreds of potheads, crack addicts, meth users, paint huffers, cokefiends, heroin junkies, pill poppers and psychiatric patients. I don't have to rely on anybody else to know how harmful it is because I've seen plenty of lives up close destroyed by pot. And I'm not even talking about health issues beyond those which are caused by some hophead driving himself into a wall or falling off the curb and busting his chin.
I'm not the right person to be trotting out the propaganda. There is no serious argument that pot is good or harmless. Neither is alcohol, neither is nicotine. I've debated the NORMAL eggheads, Michael Moore, Califano and a variety of other in the pot legalization movement. Its all been an attempt to find some legal or scientific construct to justify the desire to get high and not be judged or busted for it. Wanting a list of 'harms' is another cannard so you can trot out a bunch of seemingly scientific studies disputing facts that every pothead knows is true. Let me guess, you can 'prove' that its not even addictive??? Reminds me of those cranks who claims that the IRS is illegal and the Constitution doesn't require citizens to pay income tax on their salaries.
And these initiatives are complete bullsh!t and any remotely honest person has to admit this. If it was really such a great idea, they wouldn't have to lie constantly or create bankshots to try to get people to support it. If you or they can't just admit that you want to get high, then the demand for intellectual honesty needs to be on the other side of the table.
Wow. Four paragraphs of ranting and you couldn't come up with one single example...
I'm not asking you to generate an exhaustive list. Just pick the top 3 or something.
