Hi, I m a 21 year old male. Since September (6months) I ve been an avid smoker of marijuana. I found myself smoking at all times of the day and spending around an ounce a week, I find myself smoking when I woke, before and sometimes during work and then heavily at night. This happened for months and I was fine, however, after smoking for several hours with my friends I d go home and smoke a big joint on my own and then sleep. During this period (6 months) I found myself rarely eating and smoking heavily... I almost substituted the weed for food and found myself eating once a day at best. My weight drastically dropped and I ve lost around a stone and a half. Just over 10 stone (I m around 6 1). About a week ago I was smoking normally and after work I came back and smoked for a few hours with my friend. As usual, I barely ate... Once I got to my room, I smoked another long joint by myself in bed and found my heart rate was very low. This began to worry me as I felt around 50 (bpm) and then I started to panick and found myself struggling for breath, shaking, sweating and losing vision (I felt as if I was about to pass out as everything went white). I went to the hospital the next day and they checked my blood pressure, sugar levels and heart rate and I was told it was just above 60 which is considered okay. They also told me that the subsequent reaction to the lowering heart rate was anxiety attacks. I haven t smoked since but I often feel my heart rate is low around 50 (unless I m active). Before September, I was a regular at the gym (everyday - sometimes twice a day) and I did both weights and cardio - however, I still smoked everyday. Is this a cause for concern? Or are the doctors right in saying its anxiety rather than heart problems? I don t often feel any palpitations but sometimes I feel a strain in my chest but it s easily corrected through controlled breathing which leads me to believe its anxiety. Will continuous smoking endanger me? I m planning on waiting a few weeks, correcting my eating pattern and increasing my weight (whilst introducing daily cardio at the gym). However, I m going to build up my cardio slowly, as I don t want to go from one extreme to the other. Will regular eating (and a balanced diet) allow me to smoke daily? Or will this further affect my heart rate? Thank you
