LOL. So the big risk of marijuana is that it might lead to smoking tobacco or drinking alcohol? What kind of nonsensical reasoning is this? If the tobacco and alcohol are a problem, why not make those illegal instead?
Love the way you craftily left out the sentences that immediately followed, “After researchers adjusted the analysis to account for these factors, marijuana use was independently associated with a 26 percent increase in the risk of stroke and a 10 percent increase in the risk of developing heart failure.”
Maybe you should try reading the entire paragraph when you are not stoned; it might not seem so funny but it might have some additional meaning.
