MDMA is not legal yet but there is interest in using in in therapy (especially for couples). The ecstasy I took 20 years ago was probably cut with something nasty which is a reason to only do legal stuff.
You can legally buy shrooms online in Canada - here are two links:
Magic Mushrooms Dispensary | Buy Magic Mushrooms Online in Canada ;
Buy Weed Online Canada at Quadzilla Cannabis Online Dispensary. MMD takes a week to ship and Quadzilla can home deliver in a few hours.
I think my brain chemistry is a little different. I had ADHD as a kid (thankfully that was before they prescribed Ritalin to children). THC makes me intoxicated and stupid and gives me a holiday for a few hours from the stressors in my life, reduces mental chatter and allows me to concentrate on whatever I am enjoying at the time. My body is pretty beat up from doing martial arts for a long time and THC makes the pain go away and I sleep very well. Shrooms make me intoxicated and very mentally alert at the same time. Unlike other people I do not get much in the way of visuals or get the giggles. That alertness stays with me for days afterwards. When I do shrooms old trauma sometimes swims up from my subconscious, and in consciously reliving trauma somehow it becomes less powerful, less of an impediment to me. It is like accelerated therapy. Shrooms have also led to some good ideas for my business. It is always a crapshoot - sometimes great results, sometimes not much at all. I have not tried micro-dosing but I can see the value in it.
A word of caution - everyone is different so start with a low dose and pay attention to what you feel. And stay home.
