The banned-substances list at every competitive level matters more than most HS families realize. By the time a kid is being recruited, even a minor positive test for an inadvertent substance can affect eligibility, scholarship, and reputation.

Most kids never face a drug test. Some do. The framework below is what families should know.

The frameworks, briefly.

USADA. United States Anti-Doping Agency. Tests Olympic-track, USA-team athletes, and oversees the U.S. component of the WADA Code. Highest level, most extensive list.

WADA. World Anti-Doping Agency. International framework. The full Prohibited List is updated annually. Available at wada-ama.org.

NCAA. National Collegiate Athletic Association. Tests college athletes. NCAA’s banned-substance list overlaps with WADA but has some differences (notably caffeine has a threshold rather than a flat ban).

NFHS / state HS associations. High school testing varies by state. A minority of states test HS athletes routinely. Most do not test but follow NFHS guidance on prohibited substances.

For HS athletes being recruited to NCAA programs, the NCAA list is the relevant one for the future. For HS athletes currently competing, the state HS association’s list is the immediate one.

The categories on the banned lists.

Anabolic agents. Steroids, prohormones, SARMs (selective androgen receptor modulators). Always banned at every level.

Peptide hormones, growth factors. HGH, EPO, IGF-1, and related compounds. Always banned.

Stimulants. Amphetamines (Adderall and related ADHD medications), ephedra, methylhexanamine, cocaine. ADHD medications have Therapeutic Use Exemption pathways (see ADHD section below).

Diuretics and masking agents. Banned because they can dilute samples and mask other substances.

Cannabinoids. Marijuana and synthetic cannabinoids. NCAA testing thresholds have changed over recent years; cannabis is now treated less strictly at the NCAA level but is still on the list. Olympic-track testing more strict.

Glucocorticoids (in-competition). Some forms of corticosteroid use are restricted.

Beta blockers (in specific sports). Banned in shooting, archery, and a few others.

Erythropoiesis-stimulating agents. EPO and related.

Specific substances vary by year. Annual review of the published list is appropriate for serious athletes.

The supplement-contamination pathway.

The most-common cause of inadvertent positive tests is not deliberate doping. It is contaminated supplements.

USADA’s Supplement 411 program documents repeated cases where athletes tested positive for substances they did not knowingly take because their supplement contained undisclosed ingredients.

Common contamination categories:

Pre-workout supplements with undisclosed stimulants.

Weight-loss supplements with banned diuretics or stimulants.

“Natural” testosterone boosters with prohormones not on the label.

Protein powders with anabolic agents.

Multivitamins (rare but documented) with trace banned substances.

The fix: third-party certification for any supplement an athlete consumes. NSF Certified for Sport, Informed Sport, USP Verified. These programs test products and verify content.

Athletes who use only certified products almost never have contamination-based positives. Athletes who use uncertified supplements have a documented and meaningful risk.

The ADHD medication question.

A significant percentage of HS and college athletes have ADHD diagnoses and prescriptions for stimulant medication (Adderall, Vyvanse, Concerta, Ritalin).

The substances are banned by NCAA and most major frameworks for athletes without a documented Therapeutic Use Exemption (TUE).

The TUE process:

The athlete has a documented ADHD diagnosis from a qualified clinician.

The athlete’s school athletic department (for HS) or NCAA compliance office (for college) maintains the documentation.

For NCAA athletes, a specific TUE form must be on file before testing.

For Olympic-track athletes, the TUE process is more rigorous and managed by USADA.

A kid taking prescribed ADHD medication without the TUE paperwork in place can test positive and face consequences as if they were deliberately doping.

For HS families with an ADHD-diagnosed kid considering college athletics, the TUE process is non-optional. Talk to the school athletic department about the paperwork requirements.

The marijuana question.

State-level legalization has not changed the banned-substances framework. Most major sporting bodies still test for cannabinoids, with varying thresholds.

NCAA’s policy has been revised: cannabis is no longer on the standard banned list for performance-enhancing purposes, but is still subject to school-level policies and may be tested.

Olympic-track athletes face stricter standards. The Sha’Carri Richardson case (2021) is the prominent example of cannabis use disqualifying an Olympic athlete.

For HS athletes recruited to elite-level competition, cannabis use is a real risk.

Recreational substance considerations.

Alcohol. Generally not on banned lists for performance-enhancement testing but subject to legal age restrictions and team conduct codes.

Nicotine. Not banned but subject to team conduct.

Caffeine. Restricted but not banned in NCAA (specific threshold). Banned in some sports at specific levels. Energy-drink consumption is the primary contamination concern.

Over-the-counter cold and allergy medications. Some contain banned stimulants (pseudoephedrine, ephedrine). Athletes should verify before taking common products.

USADA’s Global DRO (dro.usada.org) is the searchable database of substances and their status by sport. Free public tool.

The testing reality.

Most HS athletes are never tested.

College athletes face testing varying by sport, conference, and individual program. Higher-profile sports (football, basketball, track and field, swimming) are tested more frequently.

Olympic-track athletes are tested extensively, including out-of-competition testing.

For a HS athlete being recruited to D1 college sport, awareness of the future testing reality is appropriate even if HS testing is unlikely.

The conversation with the kid.

The framework: “Athletes who plan to compete at college or beyond should know what is on the banned lists and how supplement contamination produces positives. The kid who avoids surprises is the kid who reads the labels and uses certified products only.”

For older athletes specifically:

Do not take any supplement that is not NSF Certified for Sport, Informed Sport, or USP Verified.

Use Global DRO to check any medication before taking.

For ADHD or other medical conditions requiring banned medication, the TUE paperwork is part of the deal.

Avoid contaminated environments (sharing supplements with friends, taking pills from teammates).

For coaches and programs.

Education at the start of each year. Most college programs do this. HS programs at competitive levels increasingly do.

A team policy on supplement use that emphasizes certified products only.

For programs with athletes on prescribed banned substances, ensure TUE paperwork is in place before testing season.

The honest read. Banned-substance issues in youth sport are rare but consequential. The kids who get caught are usually the kids who took something they did not realize was banned, often through contaminated supplements. The protective moves are simple and free: certified products only, awareness of medications, TUE paperwork for prescribed banned substances, avoidance of recreational substances that produce positives. The framework rewards being slightly more careful than seems necessary.

For the family of a HS athlete being recruited, the conversation about banned substances and supplements is part of the recruiting prep, not a separate topic.
