Would you happen to know if smoking through out the week and ingesting on the weekends would be ok, or would it just be raising my tolerance even higher.
Best guess is that as long as you don't over do it smoking during the week won't change your tolerance that much, but it is really all relative to how much you smoke. I can say that when I have tried tincture 2 days in a row the 2nd day was never as good as the first.

I have seen "run from the cure, the rick simpson story", pretty amazing stuff. I only did this once on the 1st tincture I ever made. It was with mids. I put about 2grams of dried bud in a 50ml bottle of 40% vodka and let it sit 30 days.
Then I got an empty 50ml bottle and put 2 dried grams of weed in that and poured the tincture into that bottle by placing a tea strainer in a small funnel.
Waited 30 days and repeated one more time. It was very strong and I would like to try it some time using higher end weed, 190, and waiting maybe 45 days between batches. If you buy weed on a regular basis this isn't terribly expensive to experiment with. 2 grams a month. Just a thought.

As for heating/drying the weed I have never been sure if it takes heat or just complete dehydration to convert all the chemicals in the plant to good stuff. I have gotten in the habit of breaking up a couple of grams worth of weed and letting it sit in a bowl in my cupboard for a while to dry until it crumbles into almost powder. Seems to work just as well. the other option is break it up, wrap it in paper or foil and set it on the dashboard of your car with the car facing south for a few days. Leaves a wonderful aroma in your vehicle, but it blows right out if you ride with the windows down becuse there was no smoke involved. Again, if you experiment in lots of 2-4 grams it isn't that expensive.
