So, you want drugs?
There are people that swear for cannabis.
I have recently tried the flower of datura and it do help in focus and heightening the astral senses.
Mushrooms are powerful too, and depending on your area, easy to get.
LSD, some Cactus (thought this is better do it inceremony for specific purposes).
Anyway, all I can say is that it is better do things without substances… is like paying for hoes, at first is cool, you don’t have to effort to get numbers or date or whatever, but after a while you’re not even able to get a number or have a propper date… because the brain itself neglects the necesary connections for getting a reproductive partner, just like when you stop using your muscles and get weak and fat again.
Is not worth it, and you can aslo do magick with easily attainable “altered state” (Theta-Gamma Synch). If simple staring at a sigil doesn’t do the trick for you, you can try dramatically changing your enviroment and clothes, make some excersise, and fast a bit before ritual and meditate a while with the mudra of movement (touching tips of the thumb, middle and point fingers while the other two touch the palm). That will easily get you in high awareness.
Using “little wheels” in the bike is not that cool. But if you still want to do it, I’ll say coffee combained with weed or just a few doses of datura flower (it gets you deep trance for small time but it kind of hurt your body while doing so).
