I vomit every time during intense work out

Hello. I'm not sure if this is the correct place to ask a question but I had a concern regarding my recurring vomiting while doing an intense work out.

I am a 25 year old male. I smoke regularly and drink occasionally. I also smoke marijuana daily. I used to exercise 3-5 hours a day 5 times a week from my high school years until around 4 years ago. (Football, wrestling, track during seasons and kickboxing all year around) When I used to work out, I didn't smoke, drank rarely, and smoked marijuana very rarely. I was around 150lbs when I used to work out and currently, I am 130lbs. I am slim but have athletic build. It's difficult for me to gain fat even though my diet consists of frequent fast foods.

I started going to a kickboxing gym around 6 months ago. (I've done kickboxing for 6 years before)
During regular class, I would rarely feel nausea. However, during intense exercise such as sparring, I would feel nausea and if I push my self just a little more, I end up puking. Mostly, it's just water as I eat around 6 hours before starting exercising.
I have never felt this before no matter how I pushed myself when I was very active. It's not caused by getting hit either as even when I am barely getting hit during sparring, I had to stop to vomit.
I also noticed that nausea is brought on by aerobic exercise and not anaerobic exercise as I have never felt nausea during lifting weights.

I realize that many habits have changed from when I was younger. I've picked up smoking cigarettes, drinking occasionally, and smoking marijuana daily. My diet has also changed drastically as I eat mostly what others would consider unhealthy food. Because my habits and diet has changed drastically, I cannot really pick out which habit or diet is causing my nausea during intense work out. Although I realize that quitting everything is the healthiest option, I do not want to give up everything.

I've already tried to look up the cause of my nausea. I can rule out low sodium intake as I like my food salty. I drink sips of water regularly during exercise so I doubt it's caused by dehydration.
Heat exhaustion sounds a bit probable as by the time I'm vomiting, I'm burning up although I've always felt this even when I never had to deal with my nausea.
My best guess is that the cause of my nausea is smoking cigarettes regularly. However, since this is just my amateur guess, I would like to know the cause of my nausea during intense work out.

Why am I experiencing nausea during intense work out? Please help me out so I can change my lifestyle so I won't feel this during work outs!

You want to be a competitive athlete, yet smoke, and drink, and indulge in daily weed, and live on fatty junk food, too?  

I don't think it's just one thing that's leading to your vomiting under high exertion, I think it's several things.

I suspect it's mostly the smoking (tobacco and weed), but six hours without eating seems too long so I also suggest you eat a light meal (preferrably something with a decent fiber content so it stays with you) two or three hours before competitive level exertion, and try to stay better hydrated.

Dehydration is the primary reason! It happens when your electrolyte balance is disturbed. You're producing a lot of heat when exercising so it's very important to cool off between sets for a few seconds.
If your diet is low in essential minerals and salts, it could lead to a sudden drop in sodium levels after a session of exercise, playing sports or other kinds of physical strain. As the electrolyte balance is disturbed, the body experiences nausea or vomiting.
Another cause could be your esophageal sphincter. If it's weak and the muscle relaxes involuntarily this could cause stomach acid to rush into the throat, causing anything from a slight regurgitation to nausea and vomiting.
I also suggest wearing a heart rate monitor and don't go above 85% of your   maximum heart rate.

Figure your heart rate by this formula
The Karvonen Formula is a mathematical formula that helps you determine your target heart rate zone.
The formula involves using your maximum heart rate (MHR) minus your age to come up with a target heart rate range (which is a percentage of your MHR). Staying within this range will help you work most effectively during your sparing or cardio workouts.
First thing in the morning before you get out of bed have a clock with a second hand and check your
resting heart rate then figure your rate by the Karvonen Formula

Lastly, Nausea during or after exercise may also be a sign of a hormone disorder called pheochromocytoma. Symptoms of pheochromocytoma include a high heart rate along with headaches, sweating, chest pain and feelings of anxiety. People with pheochromocytoma often feel nauseous and vomit after exercise. Consult your doctor if your nausea and high heart rate during exercise persists despite lowering the intensity of your workout and waiting three or four hours after meals to work out.
