My first 3 experiences with weed

The first 3 time si tried weed, it was a sativa (the very 1st time) and probably just straight thc the next 2 times. But for those 3 times, i felt like switching tasks was so easy. Normally, autism makes it difficult to switch between tasks, but when i was high, i felt like having a conversation or switching tasks was so easy. Could you give any explanation as to why this was?

Kava kava and liver damage, versus alcohol and liver damage

Would you care to do a deep dive on kava? I am aware that kava has been mentioned before in this AMA, but I am particularly interested in the quality and design of studies that indicate the potential for liver damage. I’ve heard on other podcasts these studies were flawed and that the noble variety of kava is safe. It would also be interesting to compare the liver damaging potential of kava to alcohol, since most of us routinely assume the risks of alcohol liver damage. Kava is also touted as a supplement that benefits sleep, contrary to alcohol, so zooming in on kava and sleep could be interesting. Lastly, is taking milk thistle capsules before a night out an effective way to protect the liver against kava and/or alcohol?

Dual n-back efficacy?

I have heard some claims that dual n-back (https://en.wikipedia.org/wiki/N-back) is a useful way to enhance certain cognitive capacities. I would be interested in your thoughts about this exercise and other brain training games or challenges. I have heard that there is limited evidence for some of the online brain training techniques marketed as improving or preserving various cognitive skills, but some claims that there is support for dual n-back.

Importance of using a script for NSDR

I tried your script (via YouTube) for NSDR and found it helpful. I am wondering, however, how important it is to use an external script on an ongoing basis. I have tried lying down and relaxing and letting my mind empty while listening to binaural beats. I fine this very restful but wonder how it might different from having guidance.

Electronic muscle stimulation

Is there any science behind electronic muscle stimulation devices (e.g. PowerDot) often used by physiotherapists to heal injuries more quickly? Can these devices help to recover more quickly from an intense workout?
