It will work, but consider:

Dry out the weed as much as possible, don't know if this is real science or voodoo but it seems to make a difference for me and a lot of other people. Grind up the weed, fold it up in a piece of paper, then put it in an Altoids tin in the sun on a hot afternoon. Preferably on a brick or cement surface. Solar drying.

With the weaker alcohol I would try to leave it soaking in about an ounce of alcohol for at least a month, longer if you can stand the temptation. Might be overkill but that would be better than underkill and poor results.

Try a teaspoon on an empty stomach. Wait 1 hour and start smoking, enjoy.
