As we posted yesterday, a conducted autopsy showed that Peep passed due to an overdose of Xanax. Since his passing, many fans have hit up his online store to score some apparel that fronts his name to keep the rapper in their memory. The merchandise was apparently sold out in minutes and TMZ reports that the team behind the clothes have run into a problem since they don't have the inventory to match the number of orders.

Those who have managed to successfully check out, have received notifications that their shipments will be significantly delayed.  

The cause of Peep's death has made many artists in the hip-hop community speak up on the drug culture that can so easily be glamourized through music. Wiz Khalifa spoke on the topic in a recent interview with Complex where he said it's unfortunate that Peep's death has to remind people of the side effects and problems with Lean.

"I just feel like somebody has to speak up for people who don't believe in that, or are really tired of seeing it," he said. "It's unfortunate that Lil Peep had to die and stuff like that, but these are the things people are gonna start seeing and keep happening if they don't really relax and fall back. I just want to be the responsible person and say something.”

Wiz later added, "I got a couple friends who do sip lean and shit, and I tell them all the time like, 'Yo, that shit is wack bro.’”

Azizi Gibson is another artist to share his opinion on the matter, speaking to fans over Snapchat.

"I'ma say this shit, stop letting this popping pills culture take away good people who just needed somebody to talk to," he said. "Don't let these fucking rappers convince you that there not about some drug when it's in their name. I had a little fuckin' cousin of mine fuckin' come to me and say 'oh, I did a few Xans here and there because one ofmyfavorite rappers talk about it all the time." He further noted how "artists have social responsibilities " and many of our favourite rappers "don't give a fuck about anything, especially you."
