Green is vapor. Red is smoke.

Three settings. Two clicks. That's the whole thing.

1. 1
   Lowest setting that still pullsClick down until the draw gets thin, then one click back up. Every click up multiplies the burn chemicals. Going from the low setting to the top of the dial made six times the methacrolein and thirty-six times the benzene in the lab.
2. 2
   Three-second drawsThe coil keeps climbing the longer you hold the button. Short draws stay in vapor. Long pulls and preheat modes are how a low setting turns into a hot one.
3. 3
   Never run it dryAn empty cart is the hottest cart there is. When the oil stops feeding the coil, the coil goes from a few hundred degrees to over a thousand. The last ten percent is the burnt ten percent.
4. 4
   Buy fresh, store coolThe metal in the oil comes from the cart itself, and it has months to seep. Don't stockpile, and don't leave carts on a hot dashboard.

A cartridge is three things.

Then there's the button. Oil has a smoke point.

You've seen it in a pan. The oil shimmers, then it smokes, and that smoke is acrolein, the stuff that stings your eyes. A cart does the same thing. On the low setting the oil turns to vapor. On the hot setting it burns, and it makes acrolein's cousin, methacrolein, plus benzene. The hotter you go, the more it makes.

Those two chemicals are the smoke alarm. Acrolein and its cousins are the reason smokers cough: they burn the lining of the airway and paralyze the little hairs that sweep the lungs clean. If a hit makes you cough, that isn't the THC. That's burnt oil hitting the same nerve a smoking pan does. And benzene is the chemical in gasoline that causes leukemia. The World Health Organization says there is no safe amount of it to breathe.

Honest part: nobody can show you a body count from this, including me. A hot puff still carries far less benzene than one cigarette. What the lab showed is a button that makes thirty-six times more of it and gives you a harsher hit for the trouble.

If the mornings are already off.

Heavy daily use has a tell, and it isn't the cough. It's the morning. Queasy before breakfast. Dry heaves. Nothing sounds good until noon, and then it passes. If that is you, this half of the page is for you.

That pattern runs down one vitamin faster than anything else. Throwing up and not eating burn through B1, and B1 is what your gut and your nerves run on. The body only holds about a month of it. It is why we replace it in the emergency department before almost anything else.

A normal week keeps the store topped up from food.

Calm is a daily, not a rescue.

It will not stop a bad morning that is already happening. It is built for the stretch in between, when intake has been poor and the gut is easy to provoke. Six actives, every dose on the label, two capsules a day.
