Not true at all. For every 1 year you can expect 1 month extra to recover fully. Every drug withdrawal group has some variation of this with different figures. An example a guy who watches porn for 2 weeks will have a much shorter reboot than one who watched porn for 24 years. That second guy will go through 2 years of PAWS and has destroyed his hormonal system. Moving away from stimulations to stimulants, Coffee stops blood flowing through specific areas of the brain and increases it flowing through other areas thats why your experience of life changes while on coffee., this is even worse, its a physical drug , but it has also destroyed other types of glands like the adrenals. You are very naive and foolisj to think you can pay back the years of being buzzed up and not experience a depression for a long long time afterwards. You have to repay it all. Its the same for most drugs, weed affects the blood flow through other areas of the brain and long term this can cause irreversable damage.
