It really scares the shit out of me reading about folks doing these dangerous chemicals. Most of them are deadly enough if they are as advertised, but you never know what is in those pills and powders. You can even get the wrong shrooms if you're not careful.

Stick to the weed!
If you need something stronger, grow some shrooms yourself.

Don't take anything someone gives you, unless you trust them with your life.
And educate your ass before you start putting things in it.
