Maybe alcohol consumption just didnt change significantly?

In anycase, here is a paper relating alcohol consumption with CRC

https://acsjournals.onlinelibrary.wiley.com/doi/10.1002/cncr.70201

This may throw some light into it... i'm a little confused in the results (english isn't my first language)

The results:

Current drinkers with an average lifetime alcohol intake of 14 or more drinks per week, compared with one drink or less per week, had a higher risk of CRC (HR, 1.25; 95% CI, 1.01–1.53), especially rectal cancer (HR, 1.95; 95% CI, 1.17–3.28). Consistent heavy drinking versus light drinking was positively associated with CRC risk (HR, 1.91; 95% CI, 1.17–3.12). Compared with current drinkers averaging less than one drink per week, former drinkers had lower odds of nonadvanced adenoma (OR, 0.58; 95% CI, 0.39–0.84). Current drinkers averaging from seven to less than 14 drinks compared with less than one drink per week had a lower risk of CRC (HR, 0.79; 95% CI, 0.64–0.97), especially distal colon cancer (HR, 0.64; 95% CI, 0.42–1.00).

14+ drinks a week sounds quite challenging. Who can drink that much?
light drinkers (1-7 a week) have lower risks or am I reading this wrong?

14 drinks is only 2 per day, 1 beer is one drink, a glass of wine is 1 drink, a whiskey shot is 1 drink. Sharing a bottle of wine with someone over dinner will by itself get you to 3 drinks for that day. Having a beer at lunch, and a single shot of whiskey after dinner will also get you to 2 drinks.

And yes according to your link, light drinkers have lower risk. Heavy drinking being positively associated with risk is not actually positive. It means the risk is higher.
In this situation positive is "statistics speak", and not about good or bad.
