I have hlhs and i smoke weed occasionally i have good lungs and eat only edibles can my heart handle the weed?

It is your brain that will have difficulty, more than your heart. Weed is a psychoactive drug and will mess with your brain. Weed users are called stoners for good reason. Abstain from street drugs, including weed. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco no alcohol.
