I ended a friendship. Now what to say?

I had a wonderful friend. He and I shared everything. He was funny and easy to get along. About a year ago he got a medical marijuana card and it became legal for him to buy a lot of marijuana. He's been high ever since. His personality has changed. He says very little now and is constantly worried about his pot supply. I was going through some things this summer and he couldn't listen to me, not even for a minute. These were things that affected him too. I gave up trying to communicate with my friend because I had to deal with the challenges I was facing. After I got through the challenges I decided I no longer wanted to be his friend. My friend made no effort to contact me during this time. He finally sent me a DM a week ago, after 4 months of no contact. He wanted to know where I have been and why I haven't frequented a place we both visit. I replied politely being vague, saying I was taking it easy due to the pandemic. The pandemic is working to my favor but sooner or later there will be a vaccine and everything will get back to normal. I expect I will run into him. How do I approach this? I really don't feel like having a heart to heart conversation. He's gone down the marijuana rabbit hole and that is his choice if that is what he wants. I can't handle his current sad personality. I'm not angry with him. I don't want to brush him off, but I am done with being his friend. Any thoughts?

I am so sorry to hear this. However, I think that your focus has to be and should be your well being and your health as number one. I know what it is like too loose friends and I understand what the pain is like to leave people. However, I also know what it is like to get out of unhealthy friendships who I thought were my friends and then seeing the satisfaction of finding new friends that are (real) that do care about me that are not focused on drinking and smoking all day and have there priorities in tack. I know this is tough for you but have too move forward and maybe he will see someday why people are leaving him left and right. I would have done the same thing if I was in your shoes. I hope this helped I wish you the best of luck! Best Wishes! Alex

And this right here is why I think they need to closely regulate medical Marijuana. I had friends that became stoners, before it was legal and they completely changed. So I understand your dilemma. In ending this friendship, you need to be honest. Tell your friend that you don't like who he is when he's high. Who knows? Maybe it will encourage him to change his habits in the long run.
