Cheap beers are becoming less cheap, and for that you can thank hipsters.

A recent study by Restaurant Sciences found that your everyday, low-cost beers like Budweiser, Miller Light and Coors Light are getting pricier, a trend the firm attributes to the rise in popularity of Pabst Blue Ribbon -- a favorite among your bearded, flannel shirt-wearing friends.

Basically, as Chuck Ellis, the head of Restaurant Sciences, put it, PBR has become "quite fashionable." This has allowed bars and restaurants to get away with charging more for the beer's low-price peers.

"I believe the single biggest driver in sub-premium beer price increases is indeed specifically PBR," Ellis told the New York Daily News.

PBR did not respond to a phone call from The Huffington Post Friday afternoon.

So how much more are you really paying? The study found that the prices of popular "sub-premium" beers have increased up to 6.8 percent in the nation's eating and drinking establishments over the past seven months (see chart below).

And it's not only beer that's getting pricier. A study out earlier this month, also by Restaurant Sciences, found that the cost of spirits and cocktails has also gotten significantly more expensive.

If this beer news makes you really angry at hipsters, you're probably not alone. A recent poll from Public Policy Polling found that only 16 percent of Americans have a favorable view of hipsters. Even more, 27 percent of Americans say hipsters should be taxed for being “so annoying.”

NEW YORK — Herbal supplements aimed at improving men's sexual abilities often contain the active ingredients in erectile dysfunction pills such as Viagra, according to a new study.

Additionally, researchers found that some of these over-the-counter herbal remedies contained more of the ingredient than is allowed in prescription-only pharmaceuticals.

"It's pretty scary stuff," said Neil Campbell, the lead author of the study and a researcher at Pfizer, which sells Viagra. "These products are not herbal at all, they're adulterated."

The U.S. Food and Drug Administration, which is in charge of regulating herbal supplements, posted 11 warnings to consumers in 2013 alerting them of unlabeled pharmaceuticals being found in these products.

Campbell and his colleagues analyzed 91 samples from 58 products.

They sent undercover consumers into convenience stores and gas stations in the Atlanta and Baltimore areas, and bought products such as Rize 2 The Occasion, Stiff 4 Hours, and Man King.

Although 57 of the products claimed to be "all natural," 81 percent of them contained tadalafil or sildenafil (marketed as Cialis and Viagra, respectively) or similar ingredients that are not approved by the FDA.

"There's so little effort to do something the right way to produce a legitimate product," Campbell said. "This is an all-time low."

None of 10 supplement companies contacted by Reuters responded to a request for comment, nor did the FDA.

Campbell said given the potential side effects and health risks associated with prescription erectile dysfunction drugs, men are "risking their lives" taking herbal sex-enhancement drugs.

"Almost one patient a day says they've tried Mojo or one of these over-the-counter products," said Dr. Gregory Lowe, an assistant professor of urology at Ohio State University who was not part of this study. "One of the big concerns is that we don't know what the patient's getting."

Seven samples that Campbell's group analyzed contained only unknown substances. It's unclear where the ingredients are coming from.
