I get high alone because of........... tobacco

To set the scene I live in London England. Over here on average and 8th is £20 and about 1.8 - 2.00g. And in europe in general there is this trend to smoke weed mixed with tobacco. This often leads to people who are weedless becoming addicted to cigarettes. I was fully aware of this before I ever smoked. Basically, I learned about weed at about the ages of 12 through internet research, I used to be able to drop facts about it, I knew why it was first made illegal, I knew al the effects it had on the body, I knew it wasnt physically but only mentally addictive(because it makes u feel good often times). I knew from an early age that I wanted to smoke weed and WEEED ONLY! And I could not fathom how in gods name cigarettes/tobacco was ever legalized! To this day I smoke only weed.
But, as I grew up and met other smokers it seems alot of weed smokers are just some unconscious/unaware drug users. They stay smoking cigarettes and wen I say to most of them "THAT shit will fucking KILLLLLLL you just hit they spliff you idiot, they always have some excuse as to why they must smoke cigarettes. Then, to top that off - alot of my smoker friend have some fake facts in their heads like "If I smoke a zoot w/cigarettes...I'm less likely to get cancer becuz of the weed". This is what all of this has lead to, I now stopped smoking weed with friends as much becuz they ALLL - literally ALLL expect two, want to mix Cigarette/chip/tobacco with the zoot.
My parents were at first against it, but since I don't bring any cigarettes into the mix. They have figured I've taken the least risk possible with the drug and am a responsible user.
Which kinda lead me to the feelings that most people who smoke weed these days ,dont actually know much about it before they try it. They just smoked weed because it was "kool", whereas me I thought it was "kool" from a much earlier age but I worked out how to take it safely. I can tell also alot of them, are getting sick of me nagging them about cigarettes habits. One friend in particular - likes to add WAYY TOOO MUCH cigg(I always end up arguing with him to take some out) to the zoots and smokes cigarettes constantly. I don't wanna sound like a bitch because I smoke the zoot with the cig in it when THEY want me too, but none of the SELFISH ASSHOLEs can put down the cigarettes in my presence. I try to explain to alot of em how the cigs has fucked up their weed experience but none of them will have it. I don't even like the little head buzz tobacco give you its fucking disgusting. Is it normal I don't want to hang around my friends wen I smoke because of this anymore? Or am I being a hypocrite since I smoke weed??? I also challenge anyone who smoke weed wiv cigs to try a small amount of weed without the cigs and see how much cleaner the high is, no anxiety, no heavy chest personally. Its just smooth sailing. I think we might have to start splitting weed wen we go halves and smoking it our own preferred ways :( i.e - my pipe/ vape pen I miss the funny group convos
