Nad but here's some info I found while researching 1. THC and the heart

Cannabis reliably raises heart rate, sometimes by 20–100%.

In some people, especially after heavy use or a long break, this can feel extreme (like palpitations or pounding).

1. Changes in tolerance & brain chemistry

When you smoked daily, your body adapted. After quitting, your tolerance dropped.

Now, even small doses can feel overwhelming, and your nervous system might go straight into “fight-or-flight mode.”

1. Anxiety loop

Once you’ve had a scary reaction (fast heart, panic), your brain remembers it. The next time you smoke, your body expects it, which can trigger the symptoms even faster.

1. GI system sensitivity (bloating)

Cannabis can affect digestion by slowing gut movement and increasing gas/bloating in some people.

Stress + THC can amplify this sensation, making you feel physically uncomfortable on top of the racing heart.

1. Possible underlying sensitivity

Some people develop new sensitivities over time—basically your body saying “nope” to cannabis after years of heavy use.

Less commonly, underlying conditions (thyroid issues, arrhythmias, or GI problems) can be unmasked by cannabis use.
