During his appearance on The Late Show with Stephen Colbert, Kevin Smith said that his doctor told him the weed he’d been smoking all day saved his life after he had a heart attack.

The weed helped to keep Smith calm, preventing him from running up his blood pressure and therefore placing more stress on his already overworked heart.

Smith told Colbert that he had been smoking bags of weed before he made it to the hospital and that he asked Dr. Ladenheim if the weed is what almost did him in.

Smith told folks that the good doctor responded with, “No! In fact, quite the opposite, that weed saved your life.”

The comic book man said that Dr. Ladenheim told him his LAD (Left Anterior Descending Artery) artery, which is also called the widow artery, was 80% block.

I know there are many of y’all asking, “What in the world does the LAD do?”

The LAD supplies blood to the heart. If the blood can’t get to the heart, then your heart can’t get oxygen. And y’all know that no oxygen equals y’all are out the door.

Luckily for Smith, Dr. Ladenheim is “good at” what he does and he made sure Smith was upright when he walked out of the hospital.

Here’s what Smith told everybody what the good doctor said, “You gonna be in the 20% because I’m good at what I do.”

Smith said that after the doctor made that comment he then disappeared into Smith’s “crotch and saved my life.”
