I don’t think drugs are a good thing, or the situation “just like” alcohol.
As noted, I think druggies are selfish losers and a danger to themselves and others.
Prohibition, however, does not work.
The alcohol model of regultion, however imperfect, is far more effective at controlling these losers.
That is a common misconseption. The 21st Annendment significantly reduced alcohol consumption in this country, but obviously the price wise to high. Pot consumption has gone up significantly everywhere it was legalized.
