ohhh i didnt even knew they where 5x and 10x, back in my days only 20x 40x 60x and 100x where sold, being a chemical sprayed over inert organic matter it seemed like the 100x was cheaper in comparison,
One thing i know for sure is that you need very high temps and energy to get a nice hit, for the best results you need a torch and a gravity bong, you can take any bong bowl and adapt to a soda cap, fill the bowl with salvia, then take the soda bottle and make a hole close to the bottom; small enough to be covered by your finger, then fill with water, place the cap and as soon as you release the finger you light the torch and keep it on until all water is gone, then wait 30 to 60 seconds for the smoke to cool down, sit down and inhale
i dont think the vape is powerful enough, even regular lighters do a louzzy job
