“Can you prove the same thing was said back then about other drugs? Sources please.”
Really, you don’t know these things? Sucks to be you.
You’re going to say that people in the 30’s were saying if alcohol was re-legalized that it would be the same as now with pot and be a slippery slope to other drugs. You need to really support that or give it up. You made that claim and if you can’t back it up, then you’re not a good debater and should be ignored.
