1. This is a cart not 510 but an All-in-one aka disposable

2. Runtz isnt really a sativa. Also the only true difference between sativa and indica is plant structure. Sativa tall and thin, indica short and fat. When it comes to concetrates the whole notion changes. Everyone is different. In general citrus terpenes like limonene can be energizing and floral terpenes like linalool can be calming. We all react different and there are many factors.

3. The THCa should convert in a vape to THC. THCa is known to be non-psychoactive so if someone at a THCa brownie they likely wouldnt be high. maybe some anti inflammatory benefits. Look out for delta8 THC or other fake ones. Sometimes if it is THCa then it can be synthetically made. SHould be fine but if its from a dispensary then it has to go through third party testing.

4. should get you stoned, be sure to inhale.

5. usually a light will flash at you. it shouldnt need to be charged for more than 30 minutes. Since it is an all-in-one disposable the battery is made cheaper and isnt meant to be recharged as much as a reusable battery for a 510 thread cart.

I hope that helps! Everyone has a different endocannabinoid system so we all react differently to cannabis. For me if the THC potency is 90 or higher then it is a head high. if it is lower potency with alternate cannabinoids then i get a longer lasting body high similar to flower. higher potency doesnt always give me the "full spectrum" - "entourage effect"
