Hi Lightdancer! i really relate to you experience with Autism Spectrum Disorder (the new term for autism; which now all of autism is Autism Spectrum Disorder); autism runs in my family. most people in my family have aspergers syndrome.
Try looking into other psychedelics for sure! many psychedelics have interesting qualities that may open one's mind. i hope to see you around in the chat btw because i'm very interested in the effects of psychedelics and ehteogens on autistic individuals.
you might consider LSA for a few reasons; primarily two reasons: empathy and entactogenesis.
LSA can create Entactogenesis and In My Experience; it's one of the most profound states of Entactogenesis i've ever been able to have the honor of experiencing. then again i've never experienced other entactogens like MDMA or even entactogenesis from psychedelics such as Psylocybin or others. Entactogenesis means "touching from within" and this heavily described LSA as an Entactogenic substance. LSA in my experience can affect alot of things like your sense of emotion and experiencing emotion.
for me; LSA was very profound. it isn't DMT by any means; but it is very profound on it's own as an experience. perhaps try it sometimes if you're interested? also have you considered using other forums like bluelight? bluelight is a really really great forum for answering a wide variety of drug questions. so is erowid. ohh and Multidisciplinary Association for Psychedelic Studies (maps)
i used LSA extensively with my sibling. LSA is best used in the presence of someone you trust or have a deep bond with; try your friend you talked to - he seems really amazing for conversation from what you described. you might also consider making the most out of LSA through doing a good preperation.
are you familiar with the basics of what an psychedelic experience is like? there's different terms of language you might want to know but i'll try to explain it the best i can.
the most basic way to describe a psychedelic experience is through a few phases; first there's the beginning and preparatory phase. this phase includes the mindset and preconscieved ideas and intentions one builds about a drug from researching the drug in question, talking to people about the drug, thinking about one's intentions for using the drug, shaping and meditating a mindset/intention bias.
sometimes it's okay to have a preconcieved intention for using a psychedelics; other times its great to go in without any intentions or anything. i would reccommend starting using LSA and doing some creative writting your first time. creative writting and psychedelics go swell together!
but then there's the actual experience; which involves set and setting. lets talk about the different types of Set(s) and Setting(s)
Perceptual Set(s) and Setting(s): Perception is what you see, hear, smell, feel, taste, and think. Perceptional Set's might include your cognitive ability to see, hear, smell, feel, taste, and think. it might include the perceptual behaviors you engage in; like listening to certain types of music or reading certain types of literature before you trip to influence your set. setting would be more along the lines of actually engaging in media's like reading, writting, listening to music, etc DURING the trip.
Cultural Set's and Setting's: culture can influence your experience greatly; whether that's a lack of cultural connectivity or if there's an abundance of it. Culture and more specifically language allows you to share idea's; which could be a part of the experience or an influencing factor. your intention of using spiritually, recreationally, or theraputically may or may not be influenced by culture.
Generally Set and Setting refers to the individual (set) and the individual's environment (setting). it's like psychology and sociology; the science of the influencing factors within (psychology) and the external influencing factors (sociology).
But then after the experience you go through a process of "integration"; which is the most important part of the experience. it's the part where you take what all you experienced into context and you learn what it means on a deeper level. Integration can include group talking; perhaps ask your friend to be willing to devote a few hours to discussing openly what you went through and how it's effected you and whether or not it changed anything about you.
integration is my favorite part of the experience; and it can last for up to months to years for some people. in my opinion, the integration process is the part that you should find most valuable.
