CBD is very expensive placebo and illegal in my state.  Kratom is effective and not illegal, and low cost.

kratomcrazy does but there's a 5% charge.

The CC companies are doing the gun ban thing with it.

They don't make statements, they just change policy and what companies they'll decide to serve or not, that's all there is to it.   Same as Google/FB/Twitter deciding only one side of an argument should be seen.  

Good start is 2-2.5g up to 3.5g for larger guys, just enough to ease the pain or get energy.  Some say as much as 5, but that's a fast track to taking it every 2 hours for the warm fuzzy.

Try to stretch it out to 4½ to 5 or even 6 hours between doses, and not every day, take 3 days a week off, don't increase the dose, don't take it more often.  Add 4 Advil and 2 Tylenol for pain, or energy drink if you're taking it for energy (if so, cut doses above by ½ or so).   Lower doses are more energizing, higher doses are more sedating, it's paradoxical that way.   People taking it for anxiety use 5g at a time, but when it wears off, the anxiety comes back as terror panic, it's a fine line.

Quitting from 50g/day is absolute suck, like stopping Tramadol cold turkey at the same time as quitting smoking for 4 days.  Then another week of ick, while all the reasons you needed it come back harder, but then back down after the 6 to 14 day mark, depending on amounts.

Try to stay under 10-15g/day and quitting isn't an issue, which is why prolonging time between and not increasing are important.  Takes months for tolerance, the rest is likely the mental side pushing you which is easy to give in to, just don't let it.

Same as going out and really limiting yourself to 2-4 beers and stopping.   Don't get plastered every night drinking.  Don't drink every night.    Same token - Don't try to get the warm fuzzy every day from kratom, and don't use it every day, just when pain is bad or extreme focus is needed.

The people that have the hardest problem with it are those with addictive personalities, and those taking it to get off hard opiate pain medicines, which it is the perfect supplement for.   The "rules" above are broken for the 2 weeks of hell coming off hard opiates just to be coherent and semi functional during withdrawal, but taper down and quit for a week or three immediately after, or you'll just have another addiction.

Do not mix with alcohol or opiates, or SNRI/SSRI, or many others, read the forums mentioned below for bad mix experiences.  We don't want anybody to be a statistic.  Stop one and start the other on days off or whatever.

In Short:  Yes, it's natural, but like EVERYTHING in life:  Moderation is Critical, especially when it's cheap (stack it deep, cheap in bulk 5kg+ each order, price is only increasing, vary strains of red/green, BTW.)

Most all of the information I have posted is from many forums from body building to chronic pain and others.   Learn all the upsides AND down sides before making a decision.  It may not be right for you.    I've basically paraphrased what I've read, the most condensed versions are at reddit's kratom and quittingkratom areas, which everybody should read to get an idea.   Lots chase the warm and fuzzy, those that do end up in quittingkratom.  Just FYI.

PS fuck reddit for their censorship of all things non left.    Kratom is one of the unique bilaterally supported topics, so expect to read a bit of leftist stuff, and don't post right wing opinions if you want a suggestion, talk about the issue, not politics other than legal status and keeping that status, and keeping them from deciding it's "Bad" after it hasn't been forever, it's been around since before the Internet, it only got really popular after Obama kicked off the opiate doctor restrictions, and high gear after Session's decided to crack down on opiates/weed/etc, so they have a new target for Control and Profit to go after.   You'll see a lot of "BigPharma", DEA, and trickle down doctor hate when reading, FYI, just skip that and get the information of experience to start.

PPS:   Take these daily along with at least 2 qt water.   Kratom depletes electrolytes, like most other drugs/alcohol due to how it's processed out of system.

(Extra tip:  Take 4 before and 4 after alcohol along with 20oz water each time to essentially kill hangovers (Drinkwel is better, but costs 5x as much))
