I find the secret is to no inject your drugs even if you do a lot, don't drink heavily for years, and stay in half decent shape
I've done lots of stims and painkillers but usually sporadically. Main drugs of choice were usually weed and halucinogens. Stay away from the opiates (IV at least) and meth kids. Or years long coke habits.
Ironically benzo usage keeps you looking younger than drinking so use benzos for similar effect on GABA receptors if you must. And benzos are calorie free so another plus.
