How do I ask a random person for drugs?

I just want to preface this by saying I’m not asking for direct sources or anything specific by any means, but I have no friends or connections, nor do I hang around anyone involved with anything fun, this is moreso asking about etiquette, because I’m on the autism spectrum and am honestly clueless.

I mainly want to find mushrooms, I grow them myself, but that takes time, and I want to trip relatively soon. I’m also a total beginner with growing, and have yet to yield a good batch. I want something from someone more skilled in the craft for the time being, but have no clue how to strike up a conversation with someone and ask if they’re into that, and then lead to the inevitable question of “ya got any?”.

I should also say that I have a pretty clean cut professional image, I definitely don’t look like I go to Burning Man, so I feel like people would think I’m a narc, but I enjoy the fungi as much as the diehard hippie, no popo here.

My last resort is to drive all the fucking way to Colorado and get them legally, but I already drive enough, and I’m pretty sure my boss would ask me why I took the company car all the way to Colorado without making up some BS camping trip story, which alone would seem kinda sus, I don’t have a girly friend. I have my own car, but I’m a cheap ass and keep it parked, and only buy insurance on a monthly basis for a single month at a time, not all year, well, just the storage policy because PA wants to suck your wallet dry even if it’s on blocks with no battery, but it’s cheap enough. So, I just use my company car all the time, but Colorado; idk.

How does a nerdy 30 year old dude with no friends ask for drugs properly? Thanks for any help
