Excellent to hear.
The closest options, both which I am aiming for personally, are medicinal chemist and pharmacologist. The former will allow you to synthesize newer drugs and send them off to be researched. The latter is allowed to research drugs on animals or cells for various purposes. If they have the chemistry background, they can do both.
I don't think any medicinal chemist will be able to do what Dr. Shulgin did in the 60~70s due to different legal situations then. Even if you do get a Schedule I license to posses these compounds where would your funding come from? I'm not familiar of any non-pharmacologist doing this type of research. Chemistry is merely the tip of the iceberg required to fully understand these (or any other drug) and suggest you read into pharmacology if you have the passion.
I've been interested in serotonin research for many years, especially 5-HT2A agonists (d-LSD, 25x-NBMeO, 2C-x, etc.), including receptor elucidation, heterodimerization, selective signaling, docking and so forth. If you wish to discuss this deeper feel free to send me a message.
All the best,
