Yeah [my stem’s](TSS Clear Glass Pyrex Drinking Straw Bent 8 Inch Set of 4, 9.5mm with Brush https://www.amazon.com/dp/B00LAPRQVU/ref=cm_sw_r_cp_api_ZsvFAb8V9PH46) definitely long enough I think (9") and most certainly hot enough - I've been heating it with this until that fucker is glowing, so it's got to be my snorting speed/power. I've had a few that have gone beautifully, no burn, absurdly large clouds, etc. Worth mentioning that as of the last couple days I've downgraded my heat source to a much smaller blowtorch. I've tried a few with my mouth as well, and it always tastes like ass.
