Even if the weed has a popular name like, "Purple Haze" or "White Widow" its never more than 20 dollars for a gram, 1.5-1.7 for $30 and 2.0-2.5 for $40 (depending on where you live it may be cheaper). Usually you'll get hooked up. Don't let someone try and say, "dude this is purple haze, $50 a gram". People are stupid enough to fall for that shit.
