SlowSuicide

OK..first off, hello to all who reads this I am new here and wanted to say hello on my first post, so...Hellllllloooo

Ok, I have a question and it only seemed appropriate here in the Health and Medicine forum... well recently I purchased some pot and I was wondering, is there a way to get the pot tested to make sure it is infact just pot? I have smoked a fair share of weed in the short amount of time I have been on this earth, but this weed has a odd taste, and smell, its not really bad, but odd. And the high is not bad either, its after im done smokin and relaxing, I get this wierd feeling over me, and makes me breathe irregulary(sp?), and i feel my heart beat through my chest. It is brickweed(real compact) and doesnt look half bad...im just concerned, because I dont want to find out i was smoking weed with say...PCP laced in it. I know I might be jumping the gun on this, but i just stick with the natural things in life, no man made drugs like PCP.

any help would be greatly appreciated.
Thanks in advance!
The concerned smoker,
