I did. He had a beer and a glass of wine another time. He didn't like the wine, and later we had drinks together in a club. Last month, he and I got high together in his home in Colorado. Different.
At 12, we went to New Orleans, and he walked down the street smiling, smoking the biggest cigar $10 could buy. Now he doesn't smoke or drink to drunkenness, but to have a treat. He uses pot for PTSD. Works great.
I don't advocate getting smashed but there is nothing wrong with drinking a little.
I have about i drink a week. sometimes.
