So I was reading what other people were saying and I figured - as a person who started in academia, bounced to big business, came back down to start-ups, and now firmly in the middle of canna - I’d let you know how I was feeling about your thought process.
- Consider your timeline. While cannabis is new and risky - people without the experience necessary to run a large operation have an opportunity to “do more with less” experience. That will not always be the case. When I hire someone TO REPLACE ME - I’m looking for someone who has years of experience dealing with investors/banks, years of experience working with vendors, years of experience managing teams of humans, years of experience working with plants, years of experience working in post-harvest activities (doesn’t have to be with canna). How many years, you might be asking - certainly MORE than a couple years, college, and a couple more years. And the position you are talking about working into - is one where I’d be looking to find you to replace me.
Indeed I look for these people all the time - there are a lot of candidates that meet my requirements, and you need another 5-8 years of team and managing experience to get onto that list.
- Consider your PASSION! Work is work. Jobs are just that, jobs. Managing to magically get a job that you enjoy and are passionate about - that’s BLISS. So lean into what fascinates you. What do you love about cannabis (is it just cannabis? all plants? all manufacturing? working on teams? working solo? experience with new technology? mastering specific tasks?) I would encourage you to try a couple of personality, strengths and career aptitude applications.
- Be mindful of the future - you mention finishing school (3-5 years?) and then coming back to get more experience and then you are off to the races. At 22 - you’re about 4 years behind “traditional students” which has probably given you more great real world experience. Its possible that the industry will be completely different by the time you finish (its radically different in the 9 years I’ve been doing it professionally…) and if so - is this industry still where you want to be in that future? Consider other things that will happen during that timeframe (family, other jobs, shifts in regulations, strange global happenings…)
Having considered those things - do some deeper digging into what other careers these pathways can take you. When I was in school (not that long ago, I promise…) the ones you have listed were grouped as I have them below. All plant “stuff” was part of the biology schools - with specializations, that really turned out to just be a couple of classes here and there. If you haven’t already talked to a college advisor (or just pulled the coursework requirements) you can go ahead and see just how many of the courses overlap - its possible you could legit major in all of these things, taking just a handful of extra classes to finish.
-Biology
-Plant science
-Plant biology
-Botany
This is where I went. I did not start there. I started in molecular biology and biochemistry… but once I started Organic Chemistry I knew what I loved, it was the only class I actually wanted to wake up for. Haha. So consider that as well. Chemistry has taken me through many industries, petrochemical, drug testing, clinical trials, pharma manufacturing, beverage production, cannabis, chrome tire manufacturing, ammunition production and testing, etc. Lots of random things in there - they all needed a chemist.

My ex-brother in law has a horticulture degree - he works for the parks service tending national forests. Lots of travel. Lots of nature. Good government job. He absolutely loves it.
When you think about replacing me - and you should, cause dang it, I need to retire in the next 15 years or so, so I can reach my own life goals…
Consider that first I burned some years in the Army. Then I got a 4-year degree (which took me 11 years, since I went part time and worked full-time). I built up a decade of practical experience doing all of that. And until I graduated I never made than $30k a year. After I graduated it doubled, almost overnight (within a few months) - even though I was doing the SAME JOB. So when people say it doesn’t matter - those people might be entrepreneurs or outliers - because on average its means doubling your lifetime earnings in the US.
At this point I’ve got almost 20 years of experience working in GMP and other highly regulated environments, developing products, and building facilities. I’ve just started to be on executive teams - making all the decisions and leading the leaders of the teams doing the work. I’ve had excellent mentors the whole way (such blessings, mentors!) and everyday I still question my path.
So don’t think you have to “get it right” - you can change, you can go back for more knowledge, you can switch careers (in 10 years and again in 20!), and in general you won’t ever be firmly financially secure. Most people never will be, not that it won’t happen to us, but statistically it is very improbable.
So find some classes you enjoy. Look for a mentor who has done the things you want to do before, so you can ask them about all their failures - because honestly, the only reason any of us have any success is because we know how to fail well and get up and do it again.
Good luck - and please let us all know what you decide to do! We love adventures and following along here at Future. Welcome to the Fam!
