With telehealth the US is way ahead of the curve with this one. It's easy enough to find a clinic that will prescribe the dissolvable troches for at home use, so you can use them during your own meditation/integration sessions in the comfort of your home. There is a lot of fuss about IV being more bioavailable and all that but it really is so much easier and at the end of the day you can have the same effect cheaper, safely, and no fuss when taking the troches at home. Check out the TherapeuticKetamine subreddit for recommendations.
