Ok i'm high as fuck on all sorts of drugs... keep that in mind when reading this.
You're just burnt out. You've depleted the stuffs you need to get high and psychologically it not a novel experience which plays part in producing the high.
What I would do is first, take a long break. That means no weed or hash for at least a month. This will cleanse the THC and it's metabolites out of your body, and fix your cannabinoid receptors, replenish and re-balance your neurotransmitters. Here are some things you can do to help your body along.
- Supplement with omega-3 and omega-6 fatty acids, which are precursors to eicosanoids which include endocannabinoids.
- Take Multi-vitamin/mineral.
- Diet is very important. Eat lots of protein and unsaturated fats especially.
- Meditation - Stimulates alpha brain waves which are the state of mind cannabis puts you in. Also releases dopamine and beta-endorphin. I like to do this when i'm high too.
- Avoid stress. Your body uses up endocannabinoids, norepinephrine and other neurotransmitters in response to stress.
- Organic unprocessed Cocoa. Contains alkaloids which prevent break down of or are precursors to anandamine, phenylethylamine, serotonin and dopamine which are partly responsible for producing the cannabis high (except for serotonin). Also makes a great potentiator and may help with withdrawals. I ate half of a 90% cocoa bar and it felt like I took a couple tokes of some sativa weed. Also contains potent anti-oxidants, vitamins and minerals.
- DL-phenylalanine. Will replenish PEA, dopamine, and norepinephrine. Also prevent breakdown of beta-endorphin and enkephalins. MJ affect the opioid system, which is responsible for the indirect dopaminergic effects.
- Daytime excercise. Cardio will help you sweat out the THC in your system, and help you lose weight if the munchies made you a little fat. Also will help replenish melatonin and PEA. Standing more often than sitting may be helpful.
- Darkness - stimulates melatonin production.
- Gingko biloba. I find this helps with the short-term memory impairment. Also has an MAOI effect, preventing breakdown of tryptamines and phenethylamines.
All of this will help you get through the weed-free month, and return your body to the state it was in before you started smoking. I guarantee the high will be incredible after you do this.
