If you were 40, I'd say you might be at risk, but you're only 15. However, what you're doing now is setting yourself up for being that 40-year-old who is at risk. The weed has absolutely nothing to do with it; it will not harm you. You really need to try to eat some fruits and vegetables...the high sodium isn't a big deal unless you eat high sodium foods daily. I'd say it's normal to sometimes feel gas pain in your chest but if it's happening a lot maybe you have heartburn
and need something to help calm your digestive system.
