Prolem #1...This is going to screw us all in the long run. WE have finally got people to understand that weed really is just a plant. Now we got this substance that looks and functions like a drug, has to be processed with chemicals and equipment, and there are going to be kids burning themselves and their homes trying to make this at home. People are going to concentrate and inhale other chemicals like bug repellents and ferts, eventually we will have the first weed fatality. Of course, it wont be from weed, just something in it, but you know how it will look on the evening news.
Prolem #2... If you get into dabbing, you are going to raise your tolerance. Remember when you first smoked, you got fubared and after a while it normlized and you get your regular buzz. Same with concentrates, you'll get really high, then you'll find your level just like now. Difference is, when you're out, and you know there are those times, the withdrawl is going to be that much worse for you.
Prolem #3... You're going to need lots more weed to supply your stonieness, and that gets expensive. There are also limits on plants and weight that people won't be able to abide by trying to keep up with the requirements of making the product.
