Marijuana Cures Methadone and Heroin Addiction!

“It does it for all opiates.”

“I can already feel the first comment. What the hell is he talking about? Well, Okay. During the 1860’s Cannabis/Marijuana was used in the U.S. to get addicted people off alcohol, tobacco and opium, and it was very successful in doing so. Many Civil War veterans were addicted to all three of these.

About that time, Morphine and the hypodermic syringe were invented, which gave doctors real control of pain and brought about the concept that a physician’s first obligation to his patients was to control pain. It was far nicer and safer than opium or alcohol.

The chemists went to work on opium and synthesized many different compounds, several of which were found to be more powerful, and more addicting than Morphine, the original opiate. These more powerful drugs were Oxycodone, Hydrocodone, Dilaudid, and Heroin, which is diacetyl morphine. Codeine, another opiate, was a much weaker opiate and its use has been minimal in the face of these much stronger opiates.

With heavy advertising and mouth-to-ear gossip, patients demanded the strong opiates. This brought on a real problem for physicians — give the patients the strong opiates, or they will find another doctor who will.

These strong opiates are notorious for not only causing addictions but they can easily cause death from accidental overdose or suicides, which are in the thousands. So, Doctors will give you enough to turn you into an addict. 20 pills. Then they say no. But the patient is still in pain, so the patient changes doctors, and repeats the action. Soon they realize it is easier to get drugs on the street.

The state medical boards have jumped into this mess by ordering physicians to stop writing these strong opiate prescriptions.

What is a patient to do about this?”

“Although there is a high prevalence of users who seek treatment for cannabis dependence, no accepted pharmacologic treatment is available to facilitate and maintain abstinence.

 The hypocretin/orexin system plays a critical role in drug addiction, but the potential participation of this system in the addictive properties of cannabinoids is unknown.

 We investigated…  studies were performed to evaluate dopamine extracellular levels in the nucleus accumbens after acute Δ9-tetrahydrocannabinol administration..

… role of Hcrtr-1 in the reinforcing and motivational properties of WIN55,212-2 (THC) was confirmed…

CONCLUSIONS:

These findings demonstrate that Hcrtr-1 modulates the reinforcing properties of cannabinoids, which could have a clear therapeutic interest.”

“In this study, we have investigated the effect of alcohol exposure on hepatic bile acid homeostasis and elucidated the mediatory roles of Cb1r and Crebh in this process.

We found that alcohol exposure or Cb1r-agonist 2-AG treatment increases hepatic bile acid synthesis and serum ALT, AST levels in vivo along with significant increase in Crebh gene expression and activation.

 Alcohol exposure activated Cb1r, Crebh, and perturbed bile acid homeostasis…

 Overall, our study demonstrates a novel regulatory mechanism of hepatic bile acid metabolism by alcohol via Cb1r-mediated activation of Crebh, and suggests that targeting Crebh can be of therapeutic potential in ameliorating alcohol-induced perturbation of bile acid homeostasis.”

Palmitoylethanolamide: From endogenous cannabimimetic substance to innovative medicine for the treatment of cannabis dependence.

“Palmitoylethanolamide (PEA) is a fatty acid amide showing some pharmacodynamic similarities with Δ9-tetrahydrocannabinol, the principal psychoactive compound present in the cannabis plant.

Like Δ9-tetrahydrocannabinol, PEA can produce a direct or indirect activation of cannabinoid receptors.

 Furthermore, it acts as an agonist at TRPV1 receptor.

The hypothesis is that PEA has anti-craving effects in cannabis dependent patients, is efficacious in the treatment of withdrawal symptoms, produces a reduction of cannabis consumption and is effective in the prevention of cannabis induced neurotoxicity and neuro-psychiatric disorders.”

“This study examines the role of the cannabinoid CB2 receptor (CB2 r) on the vulnerability to ethanol consumption… These results suggest that deletion of the CB2 r gene increased preference for and vulnerability to ethanol consumption…

Future studies will determine the role of CB2 r as a target for the treatment of problems related with alcohol consumption.”

Medical Cannabis Use Doesn’t Adversely Impact Substance Abuse Treatment Outcomes, Study Says

“The physician-supervised use of medical marijuana does not adversely affect the outcomes of individuals enrolled in substance abuse treatment programs, according to clinical trial data published last week in the Harm Reduction Journal.

An investigator at Humboldt State University in California assessed whether medical cannabis use was associated with negative outcomes in patients referred to a substance abuse treatment program.

The study reported that treatment outcomes for medically authorized cannabis users were comparable to those of subjects who were not supervised to use the drug.

“Cannabis use did not seem to compromise substance abuse treatment amongst the medical marijuana using group, who (based on these preliminary data) fared equal to or better than non-medical marijuana users in several important outcome categories (e.g., treatment completion, criminal justice involvement, medical concerns),” the study concluded. “This exploratory study suggests that medical marijuana … may not adversely affect positive treatment outcomes.””

Marijuana Derivative May Offer Hope in Cocaine Addiction – TIME

Posted on by

“A new study in mice has found that activating a receptor affected by marijuana can dramatically reduce cocaine consumption. The research suggests that new anti-addiction drugs might be developed using synthetic versions of cannabidiol (CBD), the marijuana component that activates the receptor—or even by using the purified natural compound itself.

Researchers formerly believed that the receptor, known as CB2, was not found in the brain and that therefore CBD had no psychoactive effects. But a growing body of research suggests otherwise. After THC, CBD is the second most prevalent active compound in marijuana.”

“Recent biochemical and post-mortem evidence suggests involvement of the endocannabinoid system in alcohol drinking behaviour and dependence…

CONCLUSION:

This study provides in vivo evidence that acute ethanol consumption is associated with enhanced endocannabinoid signalling in the NAcc, indicated by an increased CB1R binding and AEA content. In addition, chronic ethanol exposure leads to regional dysfunctions in CB1R levels, involving the hippocampus and caudate-putamen that are reversible within 2 weeks in this animal model.”

Colombia’s controversial cure for coke addicts: Give them marijuana

Posted on by

“Marijuana has long been accused of being a gateway to deadlier vices. But could cannabis be a swinging door that might also lead people away from hard drugs? That’s what this capital city is trying to find out.

In a controversial public health project, Bogota will supply marijuana to 300 addicts of bazuco, a cheap cocaine derivative that generates crack-like highs and is as addictive as heroin.

For the most desperate users, the cannabis cure may be the only way out.

“People accuse us of turning bazuco addicts into marijuana addicts but that’s an urban myth,” he said. “This program is about reducing personal harm and the risks to society.”

Authorities believe they might rescue some of the addicts by supplying them with quality controlled medical marijuana with a high THC content (the mind-altering component of marijuana), specifically selected to relieve the anxiety that comes with kicking bazuco.”

Dysregulation of Cannabinoid CB1 Receptor and Associated Signaling Networks in Brains of Cocaine Addicts and Cocaine-Treated Rodents.

The endocannabinoid system is implicated in the neurobiology of cocaine addiction. This study evaluated the status of cannabinoid CB1 and CB2 receptors, the endocytic cycle of CB1 receptors, receptor regulatory kinases (GRK), and associated signaling (mTOR and p70S6K) in brain cortex of drug abusers and cocaine- and cannabinoid-treated rodents…

 In long-term cocaine addicts, mTOR and p70S6K activations were not altered when compared with controls, indicating that CB1 receptor signaling was dampened. The dysregulation of CB1 receptor, GRK2/3/5, and mTOR/p70S6K signaling by cocaine may contribute to alterations of neuroplasticity and/or neurotoxicity in brains of cocaine addicts.”
