What happened

Researchers at UC San Diego have confirmed something that has long been suspected anecdotally: Those stoned kids in high school just don't keep up.

Why it matters

According to a recently released study involving more than 11,000 teens who were tracked from the age of 9-10 until they were 16-17, "cannabis use [is] tied to slower gains in memory, focus and thinking speed, as well as worse memory over time during key…

Common ground

Studies of illegal drug use are always complicated by ethical concerns, of course — researchers can't provide the substances to those being researched — so the scientists instead allowed the children to self-report their marijuana use.

Perspective signals

The tension in the story is sharpened by Loaded Language, Hasty Generalization: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.

Claim 1: “According to a recently released study involving more than 11,000 teens who were tracked from the age of 9-10 until they were 16-17, "cannabis use [is] tied to slower gains in memory, focus and thinking speed, as well as worse memory over time during key years of brain development."”
CORROBORATED
Multiple web search results report the core finding: a large study tracking teens (over 11,000) from ages 9-10 to 16-17 found that cannabis use is linked to slower gains in cognitive skills like memory, focus, and thinking speed during development. The evidence comes from different reporting sources summarizing the same research.

Claim 3: “The researchers' plan for now is to continue tracking the development of all the children who participated in the study into adulthood.”
SINGLE SOURCE
The web search results mention the continuation of tracking the study participants, but the evidence provided is not sufficient to confirm this plan was reported by multiple independent sources. The web search results mention the study's findings but do not provide corroborating evidence from different sources confirming the *plan* to continue tracking into adulthood.

Claim 4: “What the UCSD scientists found in their study was evidence that in a wide swath of skills, including thinking speed, the ability to focus and memory, teens who got high displayed noticeably less growth over time versus their straight peers, with the advances made by the children consuming cannabis leveling off as opposed to their counterparts, whose abilities improved over time.”
CORROBORATED
The web search results consistently summarize the finding that teens who used cannabis showed less growth over time in skills like thinking speed, focus, and memory compared to their peers whose abilities continued to improve. This pattern of finding is reported across multiple search snippets.
