THC Differences ??

Just curious.. a question?

I've read some different THC types around here.. Delta-9, what not?

I'm on supervised release for another month (for a DUI, nobody was hurt, its a short term misdemeanor).. I just took a UA. I know I passed becuz' I haven't smoked since Dece. 12th!

The UA test tests for 5 different drugs,.. Meth, Coke, Heroin, Ethanol, and "THC50"

Whats the difference?
I know there are natural levels of THC in lettuce and stuff, but you'd have to eat a whole field to test positive and what not..

TIA

well first of there is google
or you could have just asked the guy who administers the test

but im pretty sure there are a bunch of slightly different forms of THC and thats why we get different highs
a different strain is like a slightly mutated form of the same thing i guess

Google collects the data/info-requests I imput.

Matter of fact, it prolly collects the shit I type in here!

I am screwed in the future. Weed should be something VERYBAD!! next to Coke, Meth, and Heroin!

Fuck...

Delta-9 THC, where are you now..?? *pssshhhht* Over.. we only have THC50 in his urine.. Hold back the Bombers until Trial Date.. *pssshttt* Over
