Teenagers and young adults who use marijuana may be messing with their heads in ways they don’t intend.
Evidence is mounting that regular marijuana use increases the chance that a teenager will develop psychosis, a pattern of unusual thoughts or perceptions, such as believing the television is transmitting secret messages. It also increases the risk of developing schizophrenia, a disabling brain disorder that not only causes psychosis, but also problems concentrating and loss of emotional expression.
In one recent study that followed nearly 2,000 teenagers as they became young adults, young people who smoked marijuana at least five times were twice as likely to have developed psychosis over the next 10 years as those who didn’t smoke pot.
Another new paper concluded that early marijuana use could actually hasten the onset of psychosis by three years. Those most at risk are youths who already have a mother, father, or sibling with schizophrenia or some other psychotic disorder.
Young people with a parent or sibling affected by psychosis have a roughly one in 10 chance of developing the condition themselves — even if they never smoke pot. Regular marijuana use, however, doubles their risk — to a one in five chance of becoming psychotic.
In comparison, youths in families unaffected by psychosis have a seven in 1,000 chance of developing it. If they smoke pot regularly, the risk doubles to 14 in 1,000. Read more »

Although cocaine use has declined steadily since its peak in the early 1980s, public health officials estimate that about 7 million Americans used the drug at least once last year. Many of these folks are addicted to the drug, and its intense, short-lived euphoric effects mean the addiction is terribly difficult to overcome.
Addiction specialists believe existing treatment paradigms for cocaine addiction can be enhanced by a vaccine that prevents the drug from crossing the blood-brain barrier, thus blunting its euphoric effects. Scientists have worked hard to develop such a vaccine, but have had limited success so far.
About a year ago for example, Thomas Kosten and colleagues at Baylor reported partial success in a human trial of a cocaine vaccine. In that trial, 38 percent of subjects who received all five shots in the vaccine series achieved sufficient antibody levels to blunt the effects of the drug. In that subset, 53 percent of the subjects stopped using cocaine, meaning that overall, the vaccine worked about 20 percent of the time. Read more »

Doctors today are wary about treating chronic pain. One of the main worries is precipitating fatal opioid overdoses. Indeed, according to the CDC, and reported by American Medical News, “fatal opioid overdoses tripled to nearly 14,000 from 1999 to 2006 … [and] emergency department visits involving opioids more than doubled to nearly 306,000 between 2004 and 2008.”
Requiring chronic pain patients to sign pain contracts is a way to mitigate this risk. But how does that affect the doctor-patient relationship?
Indeed, a contract is an adversarial tool. Essentially, it states that a patient must comply with a strict set of rules in order to receive medications, including where and how often they obtain controlled substances, and may involve random drug testing. Break the contract and the patient is often fired from the practice. Read more »

I wish I could say that every patient encounter worked out well, that all my patients went home happy and satisfied. It would be nice, but unfortunately that is not true at all.
There are many patients who present with unrealistic expectations or an agenda which is non-therapeutic, and I am relatively straightforward and unapologetic about correcting patient’s misconceptions about the care that is or is not appropriate in the ED. Unsurprisingly, this often though not always involves narcotic medications.
Which is not to say that I am a jerk. I try to be compassionate, and I try to find alternative solutions, and I have been told that I can turn away a drug seeker more nicely than any other doctor in the department. But when it is time to say “no,” I say “no” firmly and without evasions or excuses. People don’t like to hear that, and all the more so in this “the consumer is king” environment of customer-service culture we foster in the medical industry these days.
So when I do say “no,” as nice as I try to be, some people get upset. Sometimes they escalate. They hurl insults, spit, throw themselves on the floor and throw a fit or feign unconsciousness. Read more »

The Drug Enforcement Administration (DEA) coordinat[ed] “National Prescription Drug Take-Back Day” this [past] Saturday [September 25th], encouraging people to turn in their unused prescription drugs. The agency hopes the event will help decrease rates of crime and addiction linked to prescription drug abuse, the New York Times reports.
From the DEA press release:
This initiative addresses a vital public safety and public health issue. Many Americans are not aware that medicines that languish in home cabinets are highly susceptible to diversion, misuse, and abuse. Rates of prescription drug abuse in the U.S. are increasing at alarming rates, as are the number of accidental poisonings and overdoses due to these drugs. Studies show that a majority of abused prescription drugs are obtained from family and friends, including from the home medicine cabinet. In addition, many Americans do not know how to properly dispose of their unused medicine, often flushing them down the toilet or throwing them away – both potential safety and health hazards.
