I smoked blends for a few months and I loved it. It had its benefits compared to Cannabis, for me, but then I developed a bad cough and some mocus build up. Ive been off them for about a month now and started smoking Cannabis again 2 weeks ago. My tolerance shot down so much, I love it haha. A few rips gets me lit :3 If the blends werent as bad for my windpipe, Id most likely start smoking them again and switch back to herb for a bit. Rotate the two, etc.
