Why not? It takes half an hour to make your own blend, saves you a LOT of money (Seriously, you spend 40-50x less this way), and you know what you're smoking, instead of putting your health in the hands of a shady dealer (Sure they might be a headshop but they care about you no more than a street dealer does, maybe even less since they have a bigger customer base)
Why is it that you want to spend more money to get a lesser product when you don't know what's in it?
That's like going to buy molly and going "Damn actually I want pills, but this guy only has pipes, and for 10x the price of molly, so I'll get pipes"
The only reason I could think of for you not being able to make your own blends is that you live with parents or something - if that's the case, then your best bet is to ask the people at the headshop what each blend contains, and if they don't tell you, refuse to buy it. You wouldn't buy something from a street dealer if he just goes "This gets you high if you smoke it!" would you?
its not that im oppsed to it, i just like instant gratification. so when i buy spice, i can smoke it right after. if i order pure jwh, then i have to wait and all that good stuff
Sorry didn't notice that when I was posting. So you'd rather have 50x less for the same price than wait a day? Sounds a bit weird to me unless you're pretty rich. Just order the JWH while you still have some legal bud/JWH/herb to smoke, that way when you run out you'll already have plenty ready. Problem solved
