Some days ago I had to visit 4-5 coffeeshops in one day in Haarlem where purchased only weed. So I had unexpected possibility to compare the quality of the Haarlem's pot.
WW Sativa and Indica offer well qured weed, sticky,smelly etc. Amnezia is much better as in other css and Willie's choice is not bad too. They have now Dynamite, nice fruity indica, but s a little bit hazy for me.
Birdy and Empire have comparable quality too, even in small "Take away" you can find strong Mex.haze for 9 eur.
But if you need a weed avoid coffeshops High Times and Teehuis.
High Times offers Mex Haze for 13 or 14 eur/g- but it is not Mex Haze! Looks like grass from ass, no smell and high. Santas Maria is not a Santa Maria, I know this strain! In the same way makes deals the Teehuis who offers non smokable hay under fruity indicas.
I smoked many varieties of pot in my life but what we purchased in these two css was absolutely non-smokable, sorry...
I just wonder is there any independant quality control in coffeshops?
How about new coming pot smokers? They smoked this fake as first experience and also start to think now that cannabis is evil and go after that to the street-pushers for hd or in bars for drinking.
