How does smoking cause blindness?
Weed is very strange for me. The first time I got high my vision became larger and "high definition." I normally have extremely good vision so it is strange that I have better vision when high. However, there have been times when high that I have lost vision, and been temporarily blind, but this has been like when you stand up after sitting down and your vision is shakey except amplified a ton. I now have the ability to amplify my vision without smoking weed which is pretty neat but I know of no one else that has had the same experiences as myself.
