For me the carts and dabbing is different but I use a cold start dab press and a "bottle device" for carts, the device has two quart jars with 2 carts and pens attached by some tubing so the jars are filled then once filled a plug is removed and the vapor inhaled. Neither gives me a headache but the jars definitely taste better (I have Covid right now so nothing tastes like anything) but the dab rig is easier to use. I refuse to use flame to use DMT, don't want to burn myself.
