Welcome to the Nexus!
You can ask your friend how it was extracted, the chems used, that will give us a better idea on the quality of the product, instead of showing a pic.
Here's a relevant thread.
DMT can certainly provide an amazing experience that can positively impact one's live if taking care of a few factors (set, setting, dosage, integration). That being said, Id just like to make sure you understand that, while psychedelic experiences can give perspective and allow for insights, Im not sure you should expect necessarily to "figure out life". You might also come out with more questions than answers, and even the perspective you get wont save you from the hard work you still have to do in daily life when you come back.
As for smoking it, put very little herb together with your DMT if you're going that way, the least possible just to catch the melting DMT, you dont want too much filler otherwise you wont feel much and will be a waste. Also, go very easy on the lighter, you want to avoid burning it. Large puffs, hold for as long as possible. Let us know how it goes!
Good luck!
