Not a grow ? But What the hell is legal bud?!!?

I have been smoking for over 20 years. I am a first time grower. But I have to ask a question. What the hell is legal bud? Is it mary jane without THC? Or is it a different plant all together.

Most are a concoction of different plants none of which are related to pot. They usually use a marijuana look alike and then coat it with other herbs that impart differing flavors and some mild effects.

It don't do f@ck all don't waste your money.

It's crap that does nothing but fill your lungs with herbs and spice smoke for nothing.
No-doz is closer to crank than "legal" weed is to ganja.

Random question, do police look at this shit, or can they even do anything about it?
