Yeah they are. One is less hassle, comes with no stigma and therefore no stress. "Why yes I have had a drink, officer, but just the one."
Also if you're a lightweight like me, you reach your limit at 2 pints. With cannabis? Who the hell knows, the quantities and potencies are still being standardized, and if you want to mix a lighter load you have to mix in more tobacco which is another stimulant.
No thanks, I'll have my brown lake water with 3% alcohol mixed in please.
