I don't know if this answers your question or not, but in my personal experience, marijuana was extremely helpful in overcoming my ED which I have determined to be PIED combined with anxiety. In fact, the best sex I've ever had was under the influence of Mary Jane. I wish I could give you a scientific reason why, but that is just my experience with it. However, that was when I was abusing porn daily while still maintaining a relationship. It got to the point to where I could only have sex when I was high - both from an ED standpoint and from a 'want to' standpoint. After a while, however, not even that could get me in the mood.
In regard to how it might affect your reboot, I can't answer that. I quit smoking well before I started my reboot. In general though, I would have to recommend against it. Even if it does help you with ED like it once did for me, it is nothing but a crutch - and you don't want to be reliant on any type of crutch. Also, I think putting yourself in an altered state of mind like that may put your reboot in jeopardy. Your urges to PMO may be increased, and your will power to fight against these urges may be decreased.
Proceed with caution my friend.
