I abstain from recreational drugs. It's not a moral issue for me - I'm just uncomfortable with the idea of having my perception chemically altered for fun. I prefer to be in full control of my body at all times. Besides, I've sipped alcohol as a child, and it really does taste like shit. Ultimately, even in moderation, drugs become a weakness, and I have enough of those already.
Your control is an illusion.
Varying levels of different neurotransmitters and other compounds are constantly chemically altering your perception, whether you are aware of it or not. If you want control, choose which compounds are going to make the alterations and take enough of them to swamp out the random ones.
ETA: Oh and rum and cokes are good. As long as you use plenty of good quality OP rum.
Gin and tonics are awesome on a hot day. Pina coladas are pretty fine too.
