Researchers at the University of Colorado-Boulder looked at more than 850 adults and 430 teenagers to find that alcohol – but not marijuana – led to lower brain volumes of grey and white brain tissue.
Grey matter controls brain function and white matter controls communication between the nerves in the brain.
Any reduction in volume could lead to lead to impaired function but that decreased volume was not observed in participants who only consumed the drug.
(ed:..i would just like to testify that i was addicted to heroin for almost a couple of decades – with side-dishes of cocaine/barbiturates/alcohol/tobacco etc etc..and i used cannabis to help me to both get off heroin and to handle the withdrawals..from all of those drugs…and of more significance – to stay off it/them..especially (but not only) alcohol…
in my life i have proven/confirmed that marijuana is medicine..
and this medicine should be offered free on prescription to those trying to kick opioids/’p’ – or anything..
…now..my addiction decades were the 70’s/80’s..so by any measure i am approaching/in dotage..
..and at a time of life when so many of my age-compatriots/contemporaries are on daily handfuls of pills/unctions/uppers/downers/leapers/screamers prescribed to them by the pills/unctions-industry…my only medicine is marijuana..to be taken when needed..
make of all that what you will..)
Attorney General Jeff Sessions hates marijuana—that much is clear.
He once said at a Senate hearing that the drug is a ‘very real danger’ and ‘good people don’t smoke marijuana’.
This week he stepped up his irrational distaste toward the drug with comments that not only contradict the available evidence but may undermine potentially life-saving public health efforts.
‘We think a lot of this is starting with marijuana and other drugs too’ Sessions said at a Heritage Foundation event this week.
He also seemed to downplay the DEA’s estimation that about 80 percent of heroin abusers start with prescription drugs.
Sessions’ belief that marijuana is feeding the opioid crisis flies in the face of evidence.
A study published by the Journal of the American Medical Association in 2014 found that the ten states that legalized medical marijuana between 1999 and 2010 saw significantly fewer opioid deaths compared to states that completely outlaw pot.
And in a report published just this week by the (ed:rightwing) RAND Corporation the 2014 findings were confirmed — though the new study found that the reduction in opioid deaths was the strongest in states that permitted medical marijuana dispensaries to open up.
Far from indicating that pot may pave the way for more opioid abuse and overdoses these studies and others suggest the opposite.
Marijuana may help people avoid the trap of opioid addiction.
Some argue that marijuana could be a key part of the fight against opioid abuse.
They do not smoke cannabis for relief from pain.
They smoke it for relief from everything else: from mild disappointment – the threat of gloom – the shrivelled love life – the general decline in joyfulness that comes with the increase of years.
They find that dope lightens their mood – relaxes them – makes their problems seem less problematic – untwists the wires a bit – makes them feel more in step with the world – more accepting of its vagaries – more cheerful.
In short it makes them more as they were when they were children.
Psychiatric patients treated with a substance found in cannabis – cannabidiol – showed a significant reduction in psychotic symptoms and were also more likely to be rated as ‘improved’ by their psychiatrist – our latest study shows.
Psychotic disorders affect two to three per cent of the population.
They usually begin in early adulthood and the symptoms can be lifelong.
Patients typically experience paranoia – hallucinations and a lack of motivation.
The main treatment for psychosis is antipsychotic drugs – which has been the first line of treatment since the 1950s.
These drugs are usually partially effective but in around a third of patients they don’t work at all.
They can also have significant side effects.
