First of all, why would you EVER want to unnaturally change the color of bud? the only value it can have is in sell value, and even then, you'd be selling an inferior, and potentially dangerous, product. Food-coloring may act in an unknown way in the lungs, as it might permanently stain your lungs of the color, or it might clog up your bronchia to cause serious damage to them. Very unwise, considering your lungs are VITAL for your survival, so if you smoke anything that isn't natural, you are pretty much playing with your own life. I strongly advise you do not color the bud of the plant, and if you already have, do not smoke it. Especially, don't sell it, because if it turns out to kill that individual, it's almost like you have committed murder just because you wanted to change the color of something. If it is for profit, you should not sell by color, but by quality, as selling by color is a decietful and (to me) low marketing strategy that is, again, potentially harmful to consumer's health. If you wish to have colored buds, go seek out strains that are known for producing that color (Purple: Many "Purple Hazes", I'm not going to argue if it exists or not, there is bud out there that is naturally purple. For that reason, dealers call it purple haze. I will not dispute the subject, I don't even care, purple in general is an inferior herb, to me.) Blue: Blueberry, sometimes Bubblicious. Red: Red Dragon, etc etc (just forgot the other reds...)


Of course, I'm no health expert or anything. But why do you think that even expert growers advise to flush the last two weeks for nutes? Because whatever you put in there eventually gets inside, and if you put it on the bud itself... that's just asking for trouble, or a really bad cough. Perfectly ok to EAT food-coloring, but absorption through ingestion and inhalation are two very different methods. Food coloring is alright to eat mainly because the human digestive track is rather durable, and can withstand a shitload of abuse, so a little color won't hurt. After all, people ingest alcohol and rough foods. It's even possible to pass a toy car throughout the entire system, but try stuffing a toy car down your breathing tube and see what happen. (Don't actually do it...)



The only thing that is really trustworthy out there is the product discussed above (the one that stinkyattic agreed with, that Purple Maxx.) You don't need bud to be colored, if it's some good shit, when you're high it won't make a difference (you might even think it's colored if it's really good herb)

Either way, Rant End.
