I found that with the pens/oil I have no self restraint. It's just too convenient and easy to take a quick puff anytime I would feel stressed, bored, etc. Whenever I get an oil cartridge I smoke it every day until it's gone.

Lately I switched to gummies only. It helps because I need to be more deliberate. For me they take an hour to kick in and last a few hours after that, so I know I'm making a conscience choice of whether or not I want to be stoned for the next few hour.
