What are the drug policies for the LCS?

I want to compete (eventually) but I am prescribed adderall for ADHD and do not want myself or the team to be fined in the event that legal use of it is against the rules (Not abusing said medicine to compete). I also do not want to have my prescribed medication become a factor in my potential when (or if) a team wants to examine me as a prospect. Checked the LCS Official Rules but could not find anything related to the matter. Thank you.

PS: I must take something for my ADHD as without it I am functional but cannot focus on any specific thought for too long, follow a diverse train of thought or even really decide what it is I think about. With enough focus I am able to but it hindered my school and social life so after being diagnosed by a trained psychiatrist and psychologist I started to take the prescribed medicine. If it allows insight I missed around 100 days of high school and finished with a 1.6 gpa though I had all A's, I had a bunch of 0's as well from missed assignments. Also, to address the question before it comes up, I definitely would not be able to just go without it on game days as this compounds my ADHD (in the theoretical sense that I am on a team and competing).

Edit: To add to this, I have been taking adderall for a long enough time to build up a tolerance so I don't receive the motivation, energy, extreme focus, or euphoria that one would receive if abusing the medication. To lower my tolerance I would have to abstain from it for atleast 3 days, which while possible is an extreme hindrance to a professional schedule (even to my current practice schedule). In the situation I abstained from my medication to lower my tolerance and receive the starting effects I would be relatively useless in regards to energy, mental capacity, reaction times etc. In other words, I wouldn't be able to practice at the needed level, let alone remember plays, specifics etc.
