Craxx

I usually smoke up with a close friend of mine and we buy from the same dealer. We are usually laid back people who enjoy to smoke up, but on one occasion after we smoked a few dimes something strange happened. Both of us became violent towards each other and were on the verge of fighting over the slightest little things that wouldn't bother us at all normally. I think it was possibly laced with PCP but I am unsure. Are there anyways of detecting weed laced with PCP? Also I have known my dealer for years and don't know how I should bring this up to him. I don't want to disrespect him by asking if it is laced with PCP but I also want to take care of my health. Multiple feedback would be appreciated!
