You must have missed the part of my post where I said that I am in favor of the legalization and controlled distribution of marijuana among adults. Having said that, however, I am not oblivious to the harm that marijuana use can do to SOME users.
I understand that some people react badly to certain substances. I agree with you completely on this.
But, this idea that all should submit to prohibitions because of the weaknesses of a few is crazy, & especially so if the government criminalizes the prohibitions. Rather than criminalize all, spend our capital helping the weak become stronger.
