DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Southaven, MS Mobile Drug & Alcohol Testing
I-55 North Memphis metro freight corridor · DeSoto County distribution and fulfillment centers · Manufacturing and industrial employers · Baptist Memorial Hospital workforce · Same-day dispatch available
Southaven anchors DeSoto County in the far north of Mississippi, sitting directly south of Memphis on I-55 and functioning as the Mississippi side of the Memphis-DeSoto County logistics corridor. The city has grown explosively as distribution centers, fulfillment operations, and manufacturing employers have relocated to DeSoto County to take advantage of lower costs and tax incentives while maintaining direct access to Memphis International Airport's massive FedEx hub and the I-55, I-69, and US-78 freight network. Major distribution employers including Amazon, Target, and Sephora have established large distribution facilities in the DeSoto County corridor. You already serve Tennessee including Shelby County (Memphis) - Southaven closes the Mississippi side of that same market. Baptist Memorial Hospital DeSoto anchors healthcare employer demand. OnSite Employer Testing dispatches mobile collectors to Southaven distribution centers, manufacturing plants, fleet yards, and employer sites throughout DeSoto County.
OnSite Employer Testing coordinates mobile drug testing collections at your Southaven-area facility, yard, terminal, or job site. We do not operate a clinic. Review how it works or browse all locations we serve across the region.
Southaven is Mississippi's fastest-growing city and the Memphis metro's primary Mississippi logistics and distribution suburb - an I-55 North corridor employer hub in DeSoto County where warehouse, distribution, and manufacturing testing demand mirrors the Memphis market without the Memphis competition.

Applicable Regulations - Southaven, MS
DOT-regulated employers in Southaven are primarily subject to 49 CFR Part 382 (FMCSA - motor carriers on I-55 and US-78) and 49 CFR Part 40. Distribution and fulfillment employers are predominantly non-DOT for warehouse staff but most large fulfillment operations maintain written drug testing programs driven by company policy, client contract requirements, and staffing agency standards. Mississippi's medical cannabis law (Miss. Code Ann. Section 41-137-37) does not require employers to accommodate cannabis use - explicitly protecting employer drug-free workplace policies. Employers should note that Tennessee's cannabis law on the Shelby County side of the metro is also very restrictive - the entire Memphis-DeSoto County corridor is employer-favorable from a cannabis policy standpoint. Program design remains the employer's responsibility.

Questions from employers in this region
We operate a distribution center off I-55 in Southaven with CDL drivers and non-DOT warehouse workers - can you handle both programs in one dispatch?
Yes. At booking, specify which employees are FMCSA-regulated CDL drivers and which are non-DOT warehouse staff. Our collector arrives with correct chain-of-custody documentation for each program. Provide your dock schedule and shift windows so we minimize operational disruption.
We are a staffing agency placing workers at DeSoto County fulfillment centers in Southaven - can you handle ongoing pre-employment collections at multiple sites?
Yes. Contact us to establish your program cadence, site addresses, and expected weekly volume. We dispatch to each fulfillment center location or a designated staging area. Multi-site staffing programs in the Memphis-DeSoto County corridor are a core use case for our mobile service.
Mississippi has a medical cannabis program - does that affect our Southaven distribution center policy?
No. Mississippi Code Section 41-137-37 explicitly protects employer drug-free workplace policies. You are not required to accommodate cannabis use and can act on a positive THC result under your written policy. The entire Memphis-DeSoto corridor is employer-favorable from a cannabis enforcement standpoint on both the Tennessee and Mississippi sides. Policy enforcement decisions are the employer's responsibility.
