Whats a good beauty regimen for potheads?

I smoke weed every week, but not everyday. I know that smoking weed depletes the body of vitamins and kills cells. But, I enjoy being high. I am a very successful student of pre-med at my college, and I am on a full scholarship. I enjoy weed when I draw, clean, and have fun! I try to eat a lot of fish throughout the week like Tuna, Salmon, Sardine. I also drink a lot of water, I take a hair vitamin and a multi vitamin. I eat a lot of fruits and veggies... But what other tips do you have for potheads???
