1388 +Subgroup Analysis:
1389 +
1390 +Males exhibited higher rates of cannabis use, but females reported stronger mental health impacts.
1391 +Individuals with pre-existing anxiety disorders were more likely to report problematic cannabis use.
1392 +Other Significant Data Points:
1393 +
1394 +Frequent cannabis users showed a 23% higher likelihood of developing anxiety symptoms.
1395 +Co-occurring substance use (e.g., alcohol) exacerbated negative psychological effects.
1396 +Findings
1397 +Primary Observations:
1398 +
1399 +Cannabis use was linked to higher depressive and anxiety symptoms, particularly in frequent users.
1400 +Self-medication patterns emerged among those with pre-existing mental health conditions.
1401 +Subgroup Trends:
1402 +
1403 +Early cannabis initiation (before age 16) was associated with greater mental health risks.
1404 +College-aged users reported more impairments in daily functioning due to cannabis use.
1405 +Specific Case Analysis:
1406 +
1407 +Participants with a history of childhood trauma were twice as likely to develop problematic cannabis use.
1408 +Co-use of cannabis and alcohol significantly increased impulsivity scores in the study sample.
1409 +Critique and Observations
1410 +Strengths of the Study:
1411 +

1454 +1. **General Observations:**
1455 + - The study examines reaction time data from **13 age-matched studies** spanning **1884–2004**.
1456 + - Results suggest an estimated **decline of 13.35 IQ points** over this period.
1457 +
1458 +2. **Subgroup Analysis:**
1459 + - The study found **slower reaction times in modern populations** compared to Victorian-era individuals.
1460 + - Data from **Western countries (US, UK, Canada, Australia, Finland)** were analyzed.
1461 +
1462 +3. **Other Significant Data Points:**
1463 + - The estimated **dysgenic rate is 1.21 IQ points lost per decade**.
1464 + - Meta-regression analysis confirmed a **steady secular trend in slowing reaction time**.
1465 +
1466 +-----
1467 +
1468 +## **Findings**##
1469 +
1470 +1. **Primary Observations:**
1471 + - Supports the hypothesis of **intelligence decline due to genetic and environmental factors**.
1472 + - Reaction time, a **biomarker for cognitive ability**, has slowed significantly over time.
1473 +
1474 +2. **Subgroup Trends:**
1475 + - A stronger **correlation between slower reaction time and lower general intelligence (g)**.
1476 + - Flynn effect (IQ gains) does not contradict this finding, as reaction time is a **biological, not environmental, measure**.
1477 +
1478 +3. **Specific Case Analysis:**
1479 + - Cross-national comparisons indicate a **global trend in slower reaction times**.
1480 + - Factors like **modern neurotoxin exposure** and **reduced selective pressure for intelligence** may contribute.
