Can you smoke weed on a coil?
It wont vaporize the weed if that is what you're asking. It will just burn it and it won't taste as good as if you had just held a flame to it and smoked it in a bowl.
How do you know when to change herbs in vape?
Once your herb has been thoroughly vaped, it starts to lose that sweet aroma. If you do it for long enough, it starts to take on a scent very similar to burnt popcorn, which is an unpleasant but very noticeable odor that no one likes. If you get that smell, it means that you vaped it way too much.
How long should a vape session last?
Generally, 15 to 30 seconds are enough before you take another hit, but you can wait longer, especially if you are experiencing dry hits more often. It can be hard to get used to, especially if you're previously a smoker which doesn't require you to wait for anything.
