That's good you have the self-awareness. You're kind of on the edge of NLP territory. Is it the act of smoking or is that simply your internal slang for cannabis use? Can you walk and listen to music at the same time? (Fine, maybe you need to walk someplace where you won't get hit by a car or someone on an electric scoot.)

As the other comment says: set and setting. And it works both ways, you can take some memento with you, and when you're being quiet and introspective and you're feeling good fondle some fob: a keychain, a rosary, buddhist prayer beads, some macrame you're working on, it doesn't matter. Point is later when you're in a different situation, you can replay that ritualistic behavior and it will probably reach in and remind your body, which will then remind you mind. This is human nature: it's known that e.g. humans remember / forget things when passing through doorways, and some forms of acting use cues like this especially for emotional resonance.
