Re: "Natural" drugs, specificly pot ARE addicting
Spinal taps will not reveal LSD or mushroom use. They can both be tested for with urinalysis, it's just extremely uncommon.
Once again, LSD and shrooms are NOT stored in your spine! How the fuck would they get there and where would they stay? It gets to your bloodstream, your brain, then your liver will clean it out of your blood and urine in DAYS. The metabolites are left in your hair for much, much longer.
