It’s not a matter of the degree of badness(!). Alcohol is often consumed for reasons other than intoxication, while marijuana is almost never consumed for reasons other than intoxication, except for medical uses.
The main issue is if the government has a role in this at all, and it is being fought over where is should be - in the states. The Federal government has no Constitutionally sanctioned role in this.
Other than toasting in celebration and partaking of the Eucharist, if you are Catholic, what other reasons are there to consume alcohol? How many drinkers do you know who take a few sips from a glass a few times a year?
I agree with your sentiment though. The government has no right to legislate people health, well being or productivity.
What other reasons?
The question then becomes what limits the powers of the state? Is it the state constitution that enumerates and therefore limited the powers of government?
I have no desire to trade a federal tyranny for a state tyranny.
This, like many issues of the day, is best solved by the individual and not some member of the new royalty (by that I mean government, either State or Federal).
