As others have said, have you tried a vaporizer or edibles? It may simply be that combustion isn't the ideal method of extraction for your physical needs.

Some people find that combustion actually burns off some of the active compounds that are beneficial for pain relief. I suggest finding a device that can cook to around 430F as opposed to some devices that top out at 410F. Pain relief and sedation are extracted at these higher cooking temps which is more beneficial for your needs.

Also consider the strain/supplier. Not all herb is created equal. I attended a trade show in the industry in Vegas a few years back and the dispensaries were handing out discounts and freebies to show attendees. One of the shops gave me two free $10 pre-rolls which I thought was awesome..... until I tried to cook them in my dry vaporizer only to get zero vapor! It turns out this shady dispensary was literally taking shake leftover after extracting concentrates and then selling as "pre-rolls" for $10 to unsuspecting novice users. Maybe you simply need to find a better strain for your physical needs.
