What Are The Side Effects Of Smoking Weed?

hi, so I ve been smoking weed for the past 3 or 2 years daily at least twice a day and suddenly yesterday I felt really dizzy and with nausea after I smoked what I regularly smoke and it lasted for atleast 30min I went to sleep and woke better but I don t know why this is happening, I ve suffered from asthma attacks like 3 times ever and have an emergency inhaler in case I feel short of air I usually never have this episodes, It s been like more than a year since the last time and their not really bad I just take a hit from my inhaler and my dizziness and lack of air goes away, I m just wondering if it has anything to do with my asthma or is something else? I recently moved away from home and I m living by myself so maybe my diet changed a bit but still weed gives me the munchies and I always end up eating a lot, maybe not the healthiest but I mean I eat I weight around 120pounds and im 5 7 please help, I hate feeling this way
