I just figured out how to use my GVG correctly, so the past week or so were my first spice trips ever...small doses just to test things out....the experiences were probably like a 2 or 3 on a scale out of 10....but they were still amazing. But, I noticed that once you exhale the vapor and close your eyes, my heart rate jumps like crazy. I'm assuming this is normal, but just wanted to ask.

Also, is there any advantage to holding the vapor for a longer amount of time? Is 20 seconds better than 10 seconds? Just curious.

Thx.

^^This is to be expected;if you hold it in for as long as you can, your heart rate will have noticeably increased before exhaling.One inhalation to clear the dose, held for as long as you can, gives the best results.

got it...thanks man.

Old post but I have just been reading "DMT the spirit molecule". The testing they were doing (injected different dosages from .1 to .4g) showed that your heart rate increase and blood pressure goes up as does the body temp. along with releasing something similar to cortisol and a few other things I have not heard of or looked up yet, into your blood stream. Most seemed to follow certain time limits to show and then disappear (within minutes). This was tests of purer than lab grade DMT salts. Interesting book if you have not read it even if it is just that info but there is other stuff on melatonin and the pineal gland and trip reports. I have not finished it yet.
