Hey,
@Blazinjones . I hope you don't mind me interjecting my 2 cents.
You've been on some pretty high opiate doses so tapering slowly is a must. It will take more time than you want. If your health care provider is not involved get them involved. You'll have to decide if you can tell them now about the cannabis use. At this point you may want to consider instead of removing entire doses of oxycodone just reduce the dose slowly even if you have to add one additional dose into the mix (like going from 15mg twice a day to 10 mg three times a day then every 1-2 weeks reducing ONE of those doses by 5 mg for a couple of weeks). It might look like this:
10/10/10 for two weeks
10/5/10 for two weeks
5/5/10 for two weeks
5/5/5 for two weeks
5/0/5 for two weeks
0/0/5 for two weeks
then take one every two days for two weeks, then every third day for two weeks then stop
You may want to slowly reduce the fentanyl FIRST in a similar manner, slowly moving down from 100 mcg to 75, them 50, then 25 in 2 week increments. You may even need to TEMPORARILY increase the oxycodone once you stop the fentanyl to make up for not being able to taper in the same way since it is a transdermal patch and it is either on or it's off.
The reason I suggest more frequent, if lower, doses of oxycodone is so that it never gets completely out of your system while you do this and thus reduces the withdrawal symptoms greatly for some people.
All of this should be done with your health care provider's knowledge and help as far as the tapering goes. If they are worth their salt they will work with you and your desire to taper down and off.
As for cannabis strains, there are several. You've already gotten some solid advice from some knowledgeable people, like
@SweetSue . In my readings and conversations with people and their experiences the following strains have popped up as good for pain time and again:
Northern Lights: pain, spasms, sleep - I prefer the pyramid seeds strain that has, according to True North Seedbank, 1.7% CBD, which is the highest I've found for this strain.
White Russian: Pain, relaxation, sleep
White Widow: More daytime for pain.
Blue Dream: Pain and spasms
You have some oil already and it's likely a CBD: THC ratio of 1:1 or 2:1 is likely to be a good starting point to take 3-4 four times a day, possibly more. You can always supplement this with a vape or smoke when you need something to act fast. Your dose is likely to be higher than average to be effective.
I wish you luck and we are here to help however we can.
