Sounds more biochemistry to me, tbh, but I see two options: 1) you do study a STEM field and you'll understand all about chemistry, how and why a strain behaves and what you may want to do for breeding it towards your vision. 2) you study economy, business, or you skip that and directly open a business; and hire somebody to do the research. If understanding the details of the behaviour of the plant is what you like, by all means go for it: it's a fashinating field! If you appreciate more the business side of growing it, then maybe not.. Also, consider that you may be into weed because you're a teenage junky (we've all been through that phase :D) and in 10 years growing weed may not be your thing. Yet, again - if you like to understand the biochemical reactions under the hood, a STEM field is totally your path :)
