If you use flower, look at getting a vaporizer because they're much more efficient than combustion. You use a lot less flower and get just as baked. Also you can use the AVB (already vaped bud) to make cannabutter after you've vaped it. So you'll get a lot more out of your stash.

You might also look at edibles. I notice that different ways of consuming weed hit different. So while I have a massive tolerance with flower, edibles still take me to space.

Lastly, you might look at getting a dab rig if nothing else works. Guaranteed to get you zooted.
