A body's a temple one ought not pollute

From smoke of grass to slime of slugs,
I've tasted and tried all kinds of drugs.
Most do one harm and some may enlighten,
Some bring sweet peace while others enfrighten.
A body's a temple one ought not pollute,
At least not the way I did in my yout',
But nannies beware, I refuse to give up
My coffee 'til cold hands are pried from my cup.
