Cannabis Tincture

[MasterBaker]

I plan on making cannabis tincture although I have question that needs answering.
My cannabis comes from an unknown source and I have heard of organophosphate poisoning.
[FONTroid Sans, Arial, sans-serif]How likely is organophosphate poisoning if I don't know if my weed is given pesticides and it's unlikely I can ask the grower?
I don't want to create a poison [/FONT]

can't say i've ever heard of this but around here selling garbage herb is a sure way to lose business. it looks like this organophosphate stuff has low solubility in water so turning the herb into bubble hash first then using the hash for the tincture seems to me the best solution.
