Well, I been smoking for 26 years now. I never got those that said they needed a t-break. I never smoke pot and do not get high, not ever, unless its just rag weed. I am sort of a pot snob though, and only ever smok the dank if I can help it. But the only thing I ever encountered that is close to what some sy, is, when I was buying weed, if I bought too much of the same stuff, I seemed to get immune to it a bit. I smoked about a 1/4 oz a week when I was a smoker. If I got the same stuff 3 weeks in a row, that 3rd week, just didn't seem to get me as high anymore, but as soon as it changed to something new, I was right back where I wanted to be. And reading all the people that state they need t-breaks, well, I consider myself lucky, because I am a full time stoner. I smoke before work, at lunch, after work, and all night. Always have. I live stoned. Yet I never ever have an issue with getting high. And I only need 2 or 3 bong rips to get there.
Fast foward to Feb of this year, I got my first vape. A Da Buddha Vape. I have not combusted since. And I am getting a MFLB to make sure I can vape on the go as well, cause i never ever plan to combust again. I love vaping so much. I also discovered BHO, so I vape flower, and I vape oil (With a TI Curve). Now that I am used to the DBV I absolutely use less weed, about half of what I used to. a wand just vapes and vapes and vapes. Get multiple sessions out of each wand. I have a custom glass set now for my DBV, and I have added one of their water filters (I have a bong but this thing is SO much better for vaping) that I also use as a mini bubbler oil rig and it works fantastically. Vaping thru this walter filter bubbler is incredible.
My main piece of advice about vaping and getting the most out of it is this. Grow your own weed. I have vaped "bought" weed, even good stuff, and have not achieved even close to the high that I get when I smoke my lovely self grown Lemon Skunk, which is also some of the frostiest stuff I have ever seen. I also have some Vanilla Kush that I grew, and its great bed time vape. But for me at least, there is a HUGE difference between freshly cured weed, and weed that has been traveling around a lot. Try some fresh stuff, and I think you will be pleased.
I waited so long to try vaping, because I wanted to try one first, but I finally realized no one was getting one, so I did, and I will probably never combust again. Vaper 4 life here. Peace.
