Hey man, I'm not arguing with you, have fun, but I'm just letting you know how foul this game can be, and preparing you for it. They can easily test it on the spot, and see if it has thc or not. Plus e-cig liquids don't look like that. If you have it, trust someone who has gotten busted had it, and one of these cops will know what it is.
Just get you a Magic flight launch box, learn how to use it, and you can still get high in public with most people not knowing just not as pretty as the vaporizer you're showing and it takes time to learn techniques, but you will get higher because the mflb can go higher in temperatures needed to release a lot of thc which is around 392f and with oils/hash you may need it higher, depending on how much you use and the type of vaporizer used. Also, the mflb heats up to 385f in 5 seconds and can go higher if needed, but once done cools off as soon as you stop engaging the battery. No vaporizer is that fast while still being small as hell. Those pen vaporizers don't go that high in temperatures, at the most 385f, and your mostly getting essential oils(taste,odor and effects the high) and some thc and other cannabinoids but not that much compared to other vaporizers. Why do you think you can get so many hits?. It's because the temperature is so low that it takes a long time to vape the whole bowl.
Have fun and be safe from the popo.
