CVS or CHS?

So to start things off, growing up I suffered with Cyclical Vomiting Syndrome from the age 9-12 when it then went into remission until last July. It was triggered by alcohol and I was in hospital for about a week. Now, for the past 3 years I’ve been smoking cannabis, BUT NOT chronically. I’ve been smoking maybe 4-5 days a week though. However, I’m only 19 and I’m not sure if smoking every 4-5 days for 3 years can cause CHS? I also get really bad heartburn after eating and this usually builds up 3 or so months after I recover from an episode, I’m really confused and it’s made me have to quit my job, college, etc…
