Quality of Cannabis

I am relatively new to smoking. The only weed that I have smoked is from my friend that he gets from his dealer. He says that it's really good. I remember first time I smoked it I had 3 hits from a gb with water and I was fucked up... How can I tell that what I'm smoking is good? Like if I grew weed correctly and harvested it at the right time would it be more dank than most weed in my area?

In my experience home grown is usually much better then street bought, but thats not always true. Once in a while you get a dealer that has really good stuff. As far as telling whats good......taste, smell, and being covered in crystals are 3 places to start. How it smokes if its smooth or harsh, and the high you get will tell you the whole answer.

This is a very subjective question. If it gets you fucked up then i would say it's pretty good. If it tastes like shit, then there's probably something better. I'm not sure there is a best strain. If your looking at quality control, I would look for mold, seeds, and leaves with no tric's. those are the biggies. Once you start smoking more and seeing more buds you'll put together a pretty good picture of what the spectrum is.
