It may not be as necessary as we once thought to use freebase when vaping using a device meant for e-juice specifically. The worry was always that salted forms require a much higher temperature to vaporize and aren't ideal for vaping, but that doesn't take into account the different method by which these e-juice devices function (lower temperature aerosolization into liquid droplets absorbed by the lungs). With that in mind, salted forms actually have a number of advantages, such as a likely higher bioavailbility and a PH closer to the human body, making for a better and more comfortable vaping experience. The conversation and experimentation has been going on for a few years over at DMT-Nexus. Skimming through these threads will explain it better than I could. https://forum.dmt-nexus.me/threads/dmt-fumarate-vape.360812/#post-3856001 https://forum.dmt-nexus.me/threads/dmt-salts-for-e-juice.367729/ https://forum.dmt-nexus.me/threads/5-meo-dmt-salts-for-e-juice.369640/ I actually have a lot of experience vaping 5-MeO-DMT fumarate, 5-MeO-MALT HCL, and DMT fumarate using this method, and I can vouch for the sentiment expressed in these threads. It does indeed appear to be the superior method. I realize this is going against the grain of the typical vaping advice, but I think we as people often get locked in a way of thinking and just kind of give knee-jerk responses that we've heard from others without really evaluating. In my opinion, the notion of "freebase only for vaping" is worth reconsidering in the context of an e-juice mix. As a side note, I actually don't love the ROA of vaping in general, and I'd tend to recommend something like oral or rectal administration depending on the substance. Vaping an e-juice mix definitely has an unhealthy feel. In my experience, its largest advantage is that you can continuously control the intensity of the trip in a granular way. It's great for mapping out the territory of what's possible with a substance. My body and lungs have always felt like they've paid for it afterward though.
