Hi Tyrone, welcome to the Nexus. Please take a look at the Attitude page:
Attitude Page - DMT-Nexus Wiki Particulary point 2.2:
No discussion on selling, buying, sourcing, acquiring, pricing, trading, receiving, distributing, mentioning pending deliveries or smuggling of drugs
Let's say that you came across that vape in some other way. In any case, there's no way anyone here can know what it contains. It could have DMT, it could have some research chemical, or it could have nothing but vape juice. No way to know without analyzing it.
That is one reason among others why it's recommended to extract your own. It's not difficult: if you can follow a cake recipe and take some minimum safety precautions, you can do it. And if you come across any difficulties, many people here will be able to help.
