Delta 9 is still illegal here in Tx and getting it has been too much of a hassle so I just started buying 8 'flower' instead. At first it had no real effect but it does give me that feeling of smoking something and it has worked pretty well for that (way cheaper as well). An added bonus was my tolerance decreased significantly for the real stuff. When I move to a different state or the laws change, I will just grow my own. I did try the cannabis vape pens on a trip to california, didn't really like it and had the worst cough for a good week or two afterwards. Convenience seems like the only reason to vape anything, but still not worth it IMO.
