There are some hassles with it, though. Mainly changing the screen.

Make sure you have the right sized screen, for a start. The ones I bought the 1st time at the head shop were a tad too big! Talk about frustration! I ended up cutting one down with wire cutters. Even with the right sized screens, it's a hassle. Last time the VB needed a new screen, I traded the hubby a load of dishwashing, if he'd do it. (I got the better deal!

)
You can put this insanity off by very gently running a flame through the glass thistle tube. Just use it like a chillum or pipe. Whoever does this will
most definitely get their head!

So if you have delicate lungs, get a friend to clear the screen. They will appreciate it.
And yes, dear, if you
just vape, the cough will go away. I toked for 40 years and my lungs were a mess! It took 2 weeks of vaping to have them clear as can be! Vapes are wonderful!
As to when it is "done"- that is a matter of personal taste. When ever it starts to taste burnt is the usual answer. As long as the duff comes out brown, it's OK. (Hubby and I vape the heck out of each load. Just a couple of stubborn old hippies determined to get that last molecule of THC out of the bud! lol

Butter might be the way for you to go- and keep it in the freezer. No way the kids will get into it there! I just do muffins with hemp seed for added nutrition. (read this)

You can get it at most large health food stores.
Enjoy your VB!- Granny
